| Business | Business On December 1, 2021, the Company completed its acquisition of Freehold Bancorp, MHC, Freehold Bancorp, Inc. and Freehold Bank (collectively, the "Freehold Entities" or "Freehold"). Pursuant to the terms of the Merger Agreement, Freehold Bancorp, MHC merged with and into the MHC, with the MHC as the surviving entity; and Freehold Bancorp, Inc. merged with and into Columbia Financial, with Columbia Financial as the surviving entity. In connection with the merger, Freehold Bank converted to a federal savings bank and operates as a wholly-owned subsidiary of Columbia Financial. The Company intends to merge Freehold Bank into Columbia Bank at a future date that has not yet been determined. Under the terms of the merger agreement, upon the subsequent merger of the two banks, depositors of Freehold Bank will become depositors of Columbia Bank and will have the same rights and privileges in the MHC as if their accounts had been established at Columbia Bank on the date established at Freehold Bank. The Company issued 2,591,007 shares of its common stock to the MHC, representing an amount equal to the fair value of the Freehold Entities as determined by an independent appraiser, at the effective time of the holding company mergers. On May 1, 2022, the Company completed its acquisition of RSI Bancorp, M.H.C., RSI Bancorp, Inc. and RSI Bank (collectively, the “RSI Entities” or "RSI").

| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Principles of Consolidation The accompanying consolidated financial statements include the accounts of Columbia Financial, Inc., its wholly-owned subsidiaries, Columbia Bank ("Columbia"), Freehold Bank ("Freehold"), and Columbia's wholly-owned subsidiaries, Columbia Investment Services, Inc., 2500 Broadway Corp., 1901 Residential Management Co. LLC, First Jersey Title Services, Inc., 1901 Commercial Management Co. LLC, Stewardship Realty LLC, CSB Realty Corp., and RSI Insurance Agency, Inc., (collectively, the “Company”). The accounts of the MHC are not consolidated in the consolidated financial statements of the Company. In consolidation, all intercompany accounts and transactions are eliminated. Certain reclassifications have been made in the consolidated financial statements to conform with current year classifications. The Company also owns 100% of the common stock of Stewardship Statutory Trust I, which is a trust incorporated in Delaware which was also acquired in the Company's merger with Stewardship in November 2019. In accordance with ASC Topic 810, Consolidation, this Trust was classified as a variable interest entity and did not satisfy the conditions for consolidation. Accordingly, this Trust, which owns $7.0 million of trust preferred securities, which represents 100% of the assets, is treated as an unconsolidated subsidiary. Basis of Financial Statement Presentation The consolidated financial statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), including the elimination of all significant intercompany accounts and transactions during consolidation. In preparing the consolidated financial statements, management is required to make estimates, significant judgments and assumptions that affect the reported amounts of assets and liabilities as of the dates of the Consolidated Statements of Financial Condition and Consolidated Statements of Income for the periods presented. Actual results could differ from these judgments and estimates under different conditions, resulting in a change that could have a material impact on the carrying values of our assets and liabilities and our results of operations. Material estimates that involve significant judgements and assumptions that are particularly susceptible to change are the determination of the adequacy of the allowance for credit losses, evaluation of goodwill for impairment, evaluation of other-than-temporary impairment on securities, evaluation of the need for valuation allowances on deferred tax assets, and determination of liabilities related to retirement and other post-retirement benefits. These estimates, significant judgements and assumptions are evaluated on an ongoing basis and are adjusted when facts and circumstances dictate. Illiquid credit markets, volatile securities markets, and declines in the housing market and the economy generally have combined to increase the uncertainty inherent in such estimates and assumptions. Changes in estimates resulting from continuing changes in the economic environment will be reflected in the consolidated financial statements in future periods. (2) Summary of Significant Accounting Policies (continued) Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks, interest-bearing deposits at other financial institutions and short-term investments. Securities Securities are classified as available for sale and held to maturity. Management determines the appropriate classification of securities at the time of purchase. Securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and reported at amortized cost. Securities not classified as held to maturity are classified as available for sale and carried at estimated fair value, with unrealized holding gains or losses, net of taxes, reported as a separate component of accumulated other comprehensive income or loss ("OCI") included in stockholders' equity. Effective January 1, 2022, the Company adopted the provisions of ASC 326 and modified its accounting policy for the assessment of available for sale securities for impairment. Under ASC 326 for available for sale securities, the Company first assesses whether a loss is from credit or other factors and considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost, a credit loss would be recorded through an allowance for credit losses, limited by the amount that the fair value is less than the amortized cost basis. The fair values of these securities are based on market quotations or matrix pricing as discussed in note 17. The Company evaluates securities for other-than-temporary impairment at each reporting period and more frequently when economic or market conditions warrant such evaluation. In this evaluation, if such declines were deemed other-than temporary, management would measure the total credit-related component of the unrealized loss and recognize that portion of the loss as a charge to current period earnings. The remaining portion of the unrealized loss would be recognized as an adjustment to OCI. The fair value of the securities portfolio is significantly affected by changes in interest rates. In general, as interest rates rise, the fair value of fixed-rate securities decreases and as interest rates fall, the fair value of fixed-rate securities increases. The Company determines if it has the intent to sell securities or if it more likely than not that the Company would be required to sell the securities before the anticipated recovery. If either exists, the decline in value is considered other-than-temporary and would be recognized in current period earnings. Premiums and discounts on securities are generally amortized and accreted to income over the contractual lives of the securities using the level-yield method. Premiums on callable securities are amortized to the earliest call date. Dividend and interest income are recognized when earned. Realized gains and losses are recognized when securities are sold or called based on the specific identification method. In the ordinary course of business, securities are pledged as collateral in conjunction with the Company’s borrowings, lines of credit, and public funds on deposit. Federal Home Loan Bank Stock The Banks, as members of the Federal Home Loan Bank of New York (the "FHLB"), are required to hold shares of capital stock of the FHLB based on its activities, primarily its outstanding borrowings. The investment is carried at cost, or par value, which approximates fair value. Cash dividends are reported as income. Loans Held-for-Sale Loans held-for-sale consists of loans intended for sale in the secondary market. These loans are carried at the lower of cost or estimated fair value, less costs to sell, as determined on an individual loan basis. Net unrealized losses, if any, are recognized in a valuation allowance through a charge to earnings. Origination fees and costs on loans held-for-sale are deferred and recognized on settlement dates as a component of the gain or loss on sale. Loans held-for-sale are generally sold with loan servicing rights retained by Columbia Bank. (2) Summary of Significant Accounting Policies (continued) Loans Receivable Loans receivable are carried at unpaid principal balances adjusted by unamortized premiums and unearned discounts, net deferred origination fees and costs, purchase accounting fair value adjustments and the allowance for credit losses. The Company defers loan origination fees and certain direct loan origination costs and accretes such amounts as an adjustment to the yield over the expected lives of the related loans using the level-yield method. Interest income on loans is accrued on unpaid principal balances and credited to income as earned. Premiums and discounts on loans purchased are amortized or accreted as an adjustment to yield over the contractual lives of the related loans using methodologies which approximate the level-yield method. A loan is considered delinquent when payment has not been received within 30 days of its contractual due date. Generally, a loan in designated as a non-accrual loan when the payment of interest is 90 days or more in arrears of its contractual due date. When a loan is placed on non-accrual status, any interest accrued but not received is reversed against interest income. Payments received on a non-accrual loan are either applied to the outstanding principal balance or recorded as interest income, depending on an assessment of the ability to collect the loan. Non-accruing loans are returned to accrual status after there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible. The Company identifies loans that may need to be charged-off as a loss, by reviewing all delinquent loans, classified loans and other loans that management may have concerns about collectability. On a case-by-case basis, the Company may evaluate individual loans for which it is probable, based on current information, that the Company will not collect all amounts due under the contractual terms of the loan agreement. The Company considers the population of loans in its analysis to include all multifamily and commercial real estate, construction, and commercial business loans with an outstanding balance greater than $500,000 and not accruing interest, and loan modifications. The Company also considers residential real estate, and home equity loans and advances that are not accruing or modified. Other loans may be included in the population of loans to be evaluated if management has specific information of a collateral shortfall. Loans individually analyzed are measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral if the loan is collateral dependent. Payments received on individually analyzed loans are recognized on a cash basis. Purchased Credit-Deteriorated ("PCD") Loans Loans acquired in a business combination that have experienced more-than-insignificant deterioration in credit quality since origination are considered purchased with credit deterioration (“PCD”) loans. The Company evaluated acquired loans for deterioration in credit quality based on any of, but not limited to, the following: (1) non-accrual status; (2) previously a troubled debt restructured designation; (3) risk ratings of special mention, substandard or doubtful; and (4) delinquency status. At the acquisition date, an estimate of expected credit losses was made for groups of PCD loans with similar risk characteristics and individual PCD loans without similar risk characteristics. This initial allowance for credit losses is allocated to individual PCD loans and added to the purchase price or acquisition date fair values to establish the initial amortized cost basis of the PCD loans. As the initial allowance for credit losses is added to the purchase price, there is no credit loss expense recognized upon acquisition of a PCD loan. Any difference between the unpaid principal balance of PCD loans and the amortized cost basis is considered to relate to noncredit factors and results in a discount or premium. Discounts and premiums are recognized through interest income on a level-yield method over the life of the loans. For acquired loans not deemed PCD at acquisition, the differences between the initial fair value and the unpaid principal balance are recognized as interest income on a level-yield basis over the lives of the related loans. At the acquisition date, an initial allowance for expected credit losses is estimated and recorded as credit loss expense. (2) Summary of Significant Accounting Policies (continued) Allowance for Credit Losses on Loans Receivable The determination of the allowance for credit losses (“ACL”) on loans is considered a critical accounting estimate by management because of the high degree of judgment involved in determining qualitative loss factors, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment The ACL is maintained at a level management considers adequate to provide for estimated losses and impairment based upon an evaluation of known and inherent risk in the loan portfolio. The ACL consists of two elements: (1) identification of loans that must be individually analyzed for impairment and (2) establishment of an ACL for loans collectively analyzed. Management estimates the ACL using relevant and reliable information from internal and external sources, related to past events, current conditions, and a reasonable and supportable forecast. Historical credit loss experience for both the Company and its segment-specific peers provides the basis for the estimate of expected credit losses. Credit losses over a defined period are converted to PD rate curves through the use of segment-specific LGD risk factors that convert default rates to loss severity based on industry-level, observed relationships between the two variables for each segment, primarily due to the nature of the underlying collateral. These risk factors were assessed for reasonableness against the Company’s own loss experience and adjusted in certain cases when the relationship between the Company’s historical default and loss severity deviate from that of the wider industry. The historical PD curves, together with corresponding economic conditions, establish a quantitative relationship between economic conditions and loan performance through an economic cycle. Portfolio segments are defined as the level at which an entity develops and documents a systematic methodology to determine its allowance for credit losses. Management developed segments for estimating losses based on the type of borrower and collateral which is generally based upon federal call report segmentation. The segments have been combined or sub-segments have been added as needed to ensure loans of similar risk profiles are appropriately pooled. We maintain a loan review system that provides a periodic review of the loan portfolio and the identification of individually analyzed loans. The ACL for individually analyzed loans is based on the fair value of collateral or cash flows. While management uses the best information available to make such evaluations, future adjustments to the allowance may be necessary if economic conditions differ substantially from the assumptions used in making the evaluations. The ACL quantitative allowance for each segment is measured using a discounted cash flow methodology incorporating an econometric, probability of default (“PD”) and loss given default (“LGD”) with distinct segment-specific multi-variate regression models applied. Expected credit losses are estimated over the life of the loans by measuring the difference between the net present value of modeled cash flows and amortized cost basis. Contractual cash flows over the contractual life of the loans are the basis for the modeled cash flows, adjusted for model defaults and expected prepayments and discounted at the loan-level effective interest rate. The contractual term excludes expected extensions, renewals, and modifications. Management estimates the ACL using relevant and reliable information from internal and external sources, related to past events, current conditions, and a reasonable and supportable forecast. Historical credit loss experience for both the Company and its segment-specific peers provides the basis for the estimate of expected credit losses. Credit losses over a defined period are converted to PD rate curves through the use of segment-specific LGD risk factors that convert default rates to loss severity based on industry-level, observed relationships between the two variables for each segment, primarily due to the nature of the underlying collateral. These risk factors were assessed for reasonableness against the Company’s own loss experience and adjusted in certain cases when the relationship between the Company’s historical default and loss severity deviate from that of the wider industry. The historical PD curves, together with corresponding economic conditions, establish a quantitative relationship between economic conditions and loan performance through an economic cycle. Using the historical relationship between economic conditions and loan performance, management’s expectation of future loan performance is incorporated using a single economic forecast of macroeconomic variables (i.e., unemployment, gross domestic product, vacancy, and home price index). This forecast is applied over a period that management has determined to be reasonable and supportable. Beyond the period over which management can develop or source a reasonable and supportable forecast, the model reverts to long-term average historical loss rates using a straight-line, time-based methodology. The Company's current forecast period is six quarters, with a four-quarter reversion period to long-term average historical loss rates. After quantitative considerations, management applies additional qualitative adjustments that consider the expected impact of certain factors not fully captured in the quantitative reserve. Qualitative adjustments include but are not limited to concentrations of large loan balances, delinquency trends, change in collateral values within segments, and other considerations. (2) Summary of Significant Accounting Policies (continued) Allowance for Credit Losses on Loans Receivable (continued) The ACL is established through the provision for credit losses that are charged to income, which is based upon an evaluation of estimated losses in the current loan portfolio, including the evaluation of individually analyzed loans. Charge-offs against the ACL are taken on loans where management determines that the collection of loan principal and interest is unlikely. Recoveries made on loans that have been charged-off are credited to the ACL. Although we believe we have established and maintained the ACL on loans at appropriate levels, changes in reserves may be necessary if actual economic and other conditions differ substantially from the forecast used in estimating the ACL. Our financial results are affected by the changes in and the level of the ACL. This process involves our analysis of internal and external variables, and it requires that we exercise judgment to estimate an appropriate ACL. As a result of the uncertainty associated with this subjectivity, we cannot assure the precision of the amount reserved, should we experience sizable loan losses in any particular period and/or significant changes in assumptions or economic condition. We believe the primary risks inherent in the portfolio are a general decline in the economy, a decline in real estate market values, rising unemployment, increasing vacancy rates, and increases in interest rates in the absence of economic improvement or any other such factors. Any one or a combination of these events may adversely affect a borrower's ability to repay its loan, resulting in increased delinquencies and loan losses. Accordingly, we have recorded loan credit losses at a level which is estimated to represent the current risk in its loan portfolio. Most of our non-performing assets are collateral dependent loans which are written down to the fair value of the collateral less estimated costs to sell. We continue to assess the collateral of these loans and update our appraisals on these loans on an annual basis. To the extent the property values decline, there could be additional losses on these non-performing assets, which may be material. Management considered these market conditions in deriving the estimated ACL. Should economic difficulties occur, the ultimate amount of loss could vary from our current estimate. Allowance for Credit Losses on Unfunded Commitments The Company is required to include unfunded commitments that are expected to be funded in the future within the allowance for credit loss calculation, other than those that are unconditionally cancellable. To arrive at that reserve, the reserve percentage for each applicable segment is applied to the unused portion of the expected commitment balance and is multiplied by the expected funding rate. To determine the expected funding rate, the Company uses a historical utilization rate for each segment. The allowance for credit losses for off-balance-sheet exposures is reported in other liabilities in the Consolidated Statements of Financial Condition. The liability represents an estimate of expected credit losses arising from off-balance-sheet exposures such as unfunded commitments. Modification of Loans ("Modifications") On January 1, 2023, the Company adopted ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures which eliminated the accounting guidance for troubled debt restructurings ("TDR's") while enhancing disclosure requirements for certain loan refinancing and restructuring by creditors when a borrower is experiencing financial difficulty. This guidance was applied on a prospective basis. Modifications made to borrowers experiencing financial difficulty may include principal or interest forgiveness, forbearance, interest rate reductions, term extensions, or a combination of these events intended to minimize economic loss and avoid foreclosure or repossession of collateral. The Company evaluates whether the modifications represent a new loan or a continuation of an existing loan. A modification or refinancing results in a new loan if the terms of the new loan are at least favorable to the Company and customers with similar collection risks who are not refinancing or restructuring their loan, and the modification to the terms of the loan are deemed to be more than minor. A modification is considered to be more than minor if the difference between the present value of the cash flows of the new obligation and the remaining cash flows of the original obligation, both discounted using the effective interest rate of the original debt, is 10% or greater. If a modification does not meet the definition of a new loan, the modified loan will be treated as a continuation of the existing loan and all unamortized net fees and/or costs, and any prepayment penalties will be carried forward as part of the net new loan balance. (2) Summary of Significant Accounting Policies (continued) Modification of Loans ("Modifications") (Continued) Modified loans that were accruing prior to their modification where income was reasonably assured subsequent to the modification, maintain their accrual status. Modified loans for which collectability was not reasonably assured, are placed on non-accrual status, interest accruals cease, and uncollected accrued interest is reversed and charged against current income. Non-accruing modified loans may be returned to accrual status when there is a sustained period of repayment performance (generally six consecutive months of payments), and both principal and interest are deemed collectible. Loans Sold and Serviced The Company has entered into guarantor swaps with Freddie Mac which results in improved liquidity. In these types of transactions, the Company sells mortgage loans in exchange for Freddie Mac Mortgage Participation Certificates backed exclusively by the loans sold. The Company retains the servicing of these loans. The Company also periodically sells loans to investors and continues to service such loans for a fee. Gains or losses on the sale of loans are recorded on trade date using the specific-identification method. Office Properties and Equipment Land is carried at cost. Office properties, land and building improvements, furniture and equipment, and leasehold improvements are carried at cost, less accumulated depreciation and amortization. Depreciation and amortization of office properties and equipment is computed on a straight-line basis over their estimated useful lives (generally 40 years for buildings, 10 years to 20 years for land and building improvements, 3 years to 10 years for furniture and equipment). Leasehold improvements, carried at cost, net of accumulated depreciation, are amortized over the terms of the related leases or the estimated useful lives of the assets, whichever is shorter. Major improvements are capitalized, while repairs and maintenance costs are charged to expense as incurred. Upon retirement or sale, any gain or loss is recognized as incurred. Bank-owned Life Insurance ("BOLI") Bank-owned life insurance is accounted for using the cash surrender value method and is recorded at its net realizable value. The change in the net asset value is recorded as a component of non-interest income. A deferred liability has been recorded for the estimated cost of post-retirement life insurance benefits accruing to applicable employees and directors covered by an endorsement split-dollar life insurance arrangement. Goodwill and Intangible Assets Intangible assets of the Company consist of goodwill, core deposit intangibles and mortgage servicing rights. Goodwill represents the excess of the purchase price over the fair value of net assets acquired in purchase acquisitions. In accordance with GAAP, goodwill with an indefinite useful life is not amortized, but is evaluated for impairment on an annual basis, or more frequently if events or changes in circumstances indicate potential impairment between annual measurement dates. As permitted by GAAP, the Company prepares a qualitative assessment in determining whether goodwill may be impaired. The factors considered in the assessment include macroeconomic conditions, industry and market conditions and overall financial performance of the Company, among others. The Company completed its annual goodwill impairment test as of December 31, 2023, based upon its qualitative assessment of goodwill and concluded that goodwill was not impaired and no further quantitative analysis was warranted. Core deposit intangibles represent the intangible value of depositor relationships acquired by the Company through purchase acquisitions of Stewardship, Freehold and RSI. The premiums ascribed to these deposits are amortized over their estimated useful lives. Mortgage servicing rights are recorded when purchased or when originated mortgage loans are sold, with servicing rights retained. Mortgage servicing rights are amortized on an accelerated method based upon the estimated lives of the related loans, and generally adjusted for prepayments. Mortgage servicing rights are carried at the lower of amortized cost or fair value. (2) Summary of Significant Accounting Policies (continued) Leases The Company determines if an arrangement is a lease at inception. The Company's leases primarily relate to real estate property for branches and office space. All the Company's leases are classified as operating leases and the related right-of-use asset ("ROU") and lease liability are included in other assets and , respectively on the Consolidated Statements of Financial Condition. ROU assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease arrangements. The calculated amounts of the ROU asset and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of minimum lease payments. As the Company's leases do not provide an implicit rate, the discount rate used in determining the lease liability for each individual lease is the Company's incremental borrowing rate. The present value of the lease liability may include the impact of options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options provided in the lease terms. Lease expense is recognized on a straight-line basis over the expected lease term, while variable lease payments are recognized as incurred. Lease agreements that include lease and non-lease components, such as common area maintenance charges, are accounted for separately. Post-retirement Benefits The Company provides certain health care and life insurance benefits to eligible retired employees under a Post-retirement Plan. The Company accrues the cost of retiree health care and other benefits during the employee's period of active service. Effective January 1, 2019, the Post-retirement Plan has been closed to new hires. Through the acquisition of the RSI Entities, the Company acquired a non-funded Post-retirement plan. This defined benefit post-retirement healthcare plan covers substantially all retirees and employees. Employee Benefit Plans The Company maintains a single employer, tax-qualified defined benefit pension plan (the "Pension Plan") which covers full-time employees that satisfy the Pension Plan's eligibility requirements. The benefits are based on years of service and the employee's average compensation for the highest consecutive years of employment. Effective October 1, 2018, newly hired employees are not eligible to participate in the Pension Plan as the Pension Plan has been closed to new employees as of that date. The policy is to fund at least the minimum contribution required by the Employee Retirement Income Security Act of 1974. GAAP requires an employer to: (a) recognize in its statement of financial position the over-funded or under-funded status of a defined benefit post-retirement plan measured as the difference between the fair value of plan assets and the benefit obligation; (b) measure a plan’s assets and its obligations that determine its funded status at the end of the employer’s fiscal year (with limited exceptions); and (c) recognize as a component of other comprehensive income (loss), net of tax, the actuarial gains and losses and the prior service costs and credits that arise during the period. The assets of the plan are primarily invested in fixed income and equity funds. Through the acquisition of the RSI Entities on May 1, 2022, the Company acquired a funded pension plan. The benefits are based on years of service and the employee’s compensation, as defined. The Plan was amended effective March 31, 2011, to freeze the Plan so that no employee shall commence or recommence participation in the Plan, that there shall be no further benefit accruals under the Plan, and that compensation received after the effective date shall not be recognized for any purpose under the Plan. Effective September 30, 2023, the RSI Pension Plan was merged into the Columbia Bank Pension Plan. The Company also maintains a Retirement Income Maintenance Plan (the "RIM Plan") which is a non-qualified defined benefit plan which provides benefits to all employees of the Company if their benefits under the Pension Plan are limited by Internal Revenue Code Sections 415 and 401(a)(17). Columbia Bank and Freehold Bank each have a 401(k) plan covering substantially all employees. Columbia Bank may match a percentage of the first 3.00% to 4.50% contributed by participants. Columbia's matching contribution, if any, is determined by their Board of Directors in its sole discretion. Freehold does not presently match any portion of employee contribution but may provide an annual match determined by their Board of Directors in its sole discretion. (2) Summary of Significant Accounting Policies (continued) Employee Benefit Plans (continued) Columbia Bank has an Employee Stock Ownership Plan ("ESOP"). The funds borrowed by the ESOP from the Company to purchase the Company's common stock are being repaid from Columbia Bank's contributions over a period of 20 years. The Company's common stock not allocated to participants is recorded as a reduction of stockholders' equity at cost. Compensation expense for the ESOP is based on the average price of the Company's stock and the amount of shares committed to be allocated during each period. Columbia Bank has a Supplemental Executive Retirement Plan ("SERP"). The SERP is a non-qualified plan which provides supplemental retirement benefits to eligible officers (those designated by the Board of Directors) of the Company who are prevented from receiving the full benefits contemplated by the ESOP's benefit formulas under tax law limits for tax-qualified plans. In addition, the Company maintains a stock based deferral plan (the "Stock Based Deferral Plan") for certain executives and directors. The Company records a deferred compensation equity account and corresponding contra-equity account for the cost of the shares held by the Stock Based Deferral and SERP Plans. Columbia Bank also maintains a non-qualified savings income maintenance deferred compensation plan (the "SIM Plan") that provides supplemental benefits to certain executives who are prevented from receiving the full benefits contemplated by the 401(k) Plan under tax law limits for tax-qualified plans, and a Deferred Compensation Plan for directors. Freehold Bank also sponsors a directors retirement plan, a director and executive deferred compensation plan, and a supplemental executive retirement plan for certain current and former directors and officers of the Bank. Through the acquisition of the RSI Entities, the Company also acquired an executive incentive retirement plan, a board of director and executive deferred compensation plan, a supplemental executive retirement plan, a key life insurance plan and a split-dollar life insurance plan for certain current and former directors and officers of the Bank. Derivatives The Company uses derivative financial instruments as components of its market risk management, principally to manage interest rate risk. Certain derivatives are entered into in connection with transactions with commercial customers. Derivatives are not used for speculative purposes. All derivatives are recognized as either assets or liabilities in the Consolidated Statements of Financial Condition, reported at fair value and presented on a gross basis. Until a derivative is settled, a favorable change in fair value results in an unrealized gain that is recognized as an asset, while an unfavorable change in fair value results in an unrealized loss that is recognized as a liability. The Company generally applies hedge accounting to its derivatives used for market risk management purposes. Hedge accounting is permitted only if specific criteria are met, including a requirement that a highly effective relationship exists between the derivative instrument and the hedged item, both at inception of the hedge and on an ongoing basis. Changes in the fair value of effective fair value hedges are recognized in current earnings (with the change in fair value of the hedged asset or liability also recognized in earnings). Changes in the fair value of effective cash flow hedges are recognized in other comprehensive income (loss) until earnings are affected by the variability in cash flows of the designated hedged item. Ineffective portions of hedge results are recognized in current earnings. Changes in the fair value of derivatives for which hedge accounting is not applied are recognized in current earnings. The Company formally documents at inception all relationships between the derivative instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transactions. This process includes linking all derivatives that are designated as hedges to specific assets and liabilities, or to specific firm commitments. The Company also formally assesses, both at inception of the hedge and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in the fair values or cash flows of the hedged items. If it is determined that a derivative is not highly effective or has ceased to be a highly effective hedge, the Company would discontinue hedge accounting prospectively. Gains or losses resulting from the termination of a derivative accounted for as a cash flow hedge remain in other comprehensive income (loss) and is (accreted) amortized to earnings over the remaining period of the former hedging relationship. (2) Summary of Significant Accounting Policies (continued) Derivatives (continued) Certain derivative financial instruments are offered to certain commercial banking customers to manage their risk of exposure and risk management strategies. These derivative instruments consist primarily of currency forward contracts and interest rate swap contracts. The risks associated with these transactions is mitigated by simultaneously entering into similar transactions having essentially offsetting terms with a third-party. In addition, the Company executes interest rate swaps with third parties in order to hedge the interest rate risk of short-term FHLB advances. Income Taxes The Company and its subsidiaries file consolidated federal income tax returns. Federal income taxes are allocated to each entity based on their respective contributions to taxable income of the consolidated income tax returns. Separate state income taxes are filed for the Company and its subsidiaries on either a consolidated or unconsolidated basis as required by each jurisdiction. The Company records income taxes in accordance with ASC Topic 740, Income Taxes, using the asset and liability method. Federal and state income taxes have been provided on the basis of the Company's income or loss as reported in accordance with GAAP. The amounts reflected on the Company's federal and state income tax returns differ from these provisions due principally to temporary differences in the reporting of certain items for consolidated financial statement reporting and income tax reporting purposes. Accordingly, deferred tax assets and liabilities: (i) are recognized for the estimated future tax consequences of events that have been recognized in the financial statements or tax returns; (ii) are attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases; and (iii) are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Where applicable, deferred tax assets are reduced by a valuation allowance for any portions determined not likely to be realized based on the nature and timing of these items. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income tax expense in the period that includes the enactment date. The valuation allowance is adjusted, by a charge or credit to income tax expense, as changes in facts and circumstances warrant. The Company did not have any liabilities for uncertain tax positions or any known unrecognized tax benefits at December 31, 2023 and 2022. The Company policy is to recognize interest and penalties related to unrecognized tax benefits in income tax expense in the Consolidated Statements of Income. The Company did not recognize any interest and penalties during the years ended December 31, 2023, 2022 and 2021. On July 1, 2018, New Jersey enacted legislation which adds to the state’s 9.0% Corporation Business Tax rate (i) a 2.5% surtax for periods beginning in 2018 and 2019 and (ii) a 1.5% surtax for periods beginning in 2020 and 2021. Subsequently, on September 12, 2020, New Jersey enacted legislation that restored and extended the 2.5% Corporation Business Tax surcharge to apply retroactively from January 1, 2020 through December 31, 2023. These surtaxes apply to corporations with more than $1.0 million of net income allocated to New Jersey. Comprehensive Income (Loss) Comprehensive income (loss) consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes items recorded in equity, such as unrealized gains and losses on debt securities available for sale, the noncredit component of other than temporary impairment losses on debt securities, unrealized gains and losses on derivatives, and the unfunded status and reclassification of actuarial net (loss) gain associated with the Company's benefit plans. Comprehensive income is presented in a separate Consolidated Statement of Comprehensive Income (Loss). Segment Reporting The Company’s operations are substantially in the financial services industry and include providing traditional banking and other financial services to its customers. The Company operates primarily in New Jersey. Management makes operating decisions and assesses performance based on an ongoing review of the Company’s consolidated financial results. Therefore, the Company has a single operating segment for financial reporting purposes. (2) Summary of Significant Accounting Policies (continued) Earnings Per Share ("EPS") Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. For purposes of calculating basic EPS, weighted average common shares outstanding excludes treasury stock, unallocated employee stock ownership plan shares that have not been committed for release and deferred compensation obligations required to be settled in shares of Company stock. Diluted EPS is computed using the same method as basic EPS and reflects the potential dilution which could occur if stock options and unvested shares were exercised and converted into common stock. The potentially diluted shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method. Shares issued and reacquired during any period are weighted for the portion of the period that they were outstanding. Stock Compensation Plans Compensation expense related to stock options and non-vested restricted stock awards is based on the fair value of the award on the measurement date with expense recognized on a straight line basis over the requisite performance or service period. The fair value of stock options is estimated utilizing the Black-Scholes option pricing model. The fair value of non-vested restricted stock awards is generally the closing market price of the Company's common stock on the date of grant. The Company accounts for forfeitures as they occur. Accounting Pronouncements Adopted In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method. The purpose of this updated guidance is to further align risk management objectives with hedge accounting results on the application of the last-of-layer method, which was first introduced in ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2022-01 is effective for public business entities for fiscal years beginning after December 15, 2022, with early adoption in the interim period, permitted. For entities who have already adopted ASU 2017-12, immediate adoption is allowed. ASU 2022-01 requires a modified retrospective transition method for basis adjustments in which the entity will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption. The Company adopted this ASU on January 1, 2023 on a prospective basis; therefore, there was no impact to the Company's consolidated financial statements. In March 2022, the FASB issued ASU 2022-02, Financial Instruments-Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures. ASU 2022-02 addresses areas identified by the FASB as part of its post-implementation review of the credit losses standard (ASU 2016-13) that introduced the CECL model. The amendments eliminated the accounting guidance for troubled debt restructurings by creditors that have adopted the CECL model and enhanced the disclosure requirements for loan refinancing and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require a public business entity to disclose current period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. For entities that have adopted ASU 2016-13, this ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company adopted this pronouncement effective January 1, 2023. The update was applied on a prospective basis to disclosures and did not have a significant impact on the Company's consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("CECL"), further amended by ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. Topic 326 pertains to the measurement of credit losses on financial instruments. This update requires the measurement of all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better determine their credit loss estimates. This update is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. This update was effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2019. (2) Summary of Significant Accounting Policies (continued) Accounting Pronouncements Adopted (continued The Company elected to defer the adoption of the CECL methodology until December 31, 2020 as permitted by the enacted Coronavirus Aid, Relief and Economic Security Act ("CARES Act"). In late December 2020, the Consolidated Appropriations Act, 2021 was enacted, and extended certain provisions of the CARES Act, which allowed the Company to extend the adoption of CECL until January 1, 2022. The Company elected to extend its adoption of CECL in accordance with this legislation, and adopted the above mentioned ASUs related to Financial Instruments -Credit Losses (Topic 326) using a modified retrospective approach. The Company adopted ASU 2016-13 on January 1, 2022 for all financial assets measured at amortized cost and off-balance- sheet credit exposures. Results for the year ended December 31, 2023 are presented under Accounting Standards Codification 326, Financial Instruments - Credit Losses, while prior period amounts continue to be reported with previously applicable GAAP and have not been restated. Effective January 1, 2022, the Company recorded a $12.1 million decrease in the allowance for credit losses on loans (previously allowance for loan losses), established a $353,000 allowance for credit losses on debt securities available for sale, and recorded a $5.5 million increase in the liability for off-balance-sheet credit exposures, which resulted in a total cumulative effect adjustment of $6.2 million, net of tax, and an increase to retained earnings.

| Acquisitions | Acquisitions Freehold Bank On December 1, 2021, the Company completed its acquisition of Freehold Bancorp, MHC, Freehold Bancorp, Inc. and Freehold Bank (collectively, the "Freehold Entities" or "Freehold"). Pursuant to the terms of the Merger Agreement, Freehold Bancorp, MHC merged with and into the MHC, with the MHC as the surviving entity; and Freehold Bancorp, Inc. merged with and into Columbia Financial, with Columbia Financial as the surviving entity. In connection with the merger, Freehold Bank converted to a federal savings bank and operates as a wholly-owned subsidiary of Columbia Financial. The Company intends to merge Freehold Bank into Columbia Bank at a future date that has not yet been determined. Under the terms of the merger agreement, upon the subsequent merger of the two banks, depositors of Freehold Bank will become depositors of Columbia Bank and will have the same rights and privileges in the MHC as if their accounts had been established at Columbia Bank on the date established at Freehold Bank. The Company issued 2,591,007 shares of its common stock to the MHC, representing an amount equal to the fair value of the Freehold Entities as determined by an independent appraiser, at the effective time of the holding company mergers. Merger-related expenses are recorded in the Consolidated Statements of Income and are expensed as incurred. Direct acquisition and other charges incurred in connection with the acquisition of the Freehold Entities totaled $413,000, $11,000, and $350,000 for the years ended December 31, 2023, 2022, and 2021, respectively. The following table sets forth assets acquired, and liabilities assumed in the acquisition of Freehold Entities, at their estimated fair values as of the closing date of the transaction:
(3) Acquisitions (continued) Freehold Bank (continued) The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. The assets and liabilities were recorded at their fair values as of December 1, 2021, and resulted in the recognition of goodwill of $6.1 million. The determination of the fair value of assets acquired and liabilities assumed required management to make estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and subject to change. During the third quarter of 2022, the Company completed all tax returns related to the operations of Freehold Bank and its impact on the Company's income taxes, which resulted in an adjustment of $82,000 to deferred income taxes, net, and a corresponding decrease in goodwill. At both December 31, 2023 and 2022, goodwill related to the Freehold acquisition totaled $6.0 million. RSI Bank On May 1, 2022, the Company completed its acquisition of RSI Bancorp, M.H.C., RSI Bancorp, Inc. and RSI Bank (collectively, the “RSI Entities” or "RSI"). Pursuant to the terms of the merger agreement, RSI Bancorp, M.H.C. merged with and into the MHC, with the MHC as the surviving entity; RSI Bancorp, Inc. merged with and into Columbia Financial, with Columbia Financial as the surviving entity; and RSI Bank merged with and into Columbia Bank, with Columbia Bank as the surviving institution. Under the terms of the merger agreement, depositors of RSI Bank became depositors of Columbia Bank and have the same rights and privileges in the MHC as if their accounts had been established at Columbia Bank on the date established at RSI Bank. The Company issued 6,086,314 shares of its common stock to the MHC, representing an amount equal to the discounted fair value of the RSI Entities as determined by an independent appraiser, at the effective time of the merger. Merger-related expenses are recorded in the Consolidated Statements of Income and are expensed as incurred. Direct acquisition and other charges incurred in connection with the acquisition of the RSI Entities totaled $193,000, $2.8 million and $196,000 for the years ended December 31, 2023, 2022, and 2021, respectively. (3) Acquisitions (continued) RSI Bank (continued) The following table sets forth assets acquired, and liabilities assumed in the acquisition of the RSI Entities, at their estimated fair values as of the closing date of the transaction:
The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. The assets and liabilities were recorded at their fair values as of May 1, 2022, and resulted in the recognition of goodwill of $28.0 million. The determination of the fair value of assets acquired and liabilities assumed required management to make estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and subject to change. During the third quarter of 2022, the Company completed all tax returns related to the operation of RSI Bank and its impact on the Company's income taxes, which resulted in a $2.0 million adjustment to deferred income taxes, net, and a corresponding decrease in goodwill. During the fourth quarter of, 2022, the Company recorded an adjustment of $490,922 to the original discounted fair value, which resulted in a decrease in additional paid-in-capital, and a corresponding decrease in goodwill. At both December 31, 2023 and 2022, goodwill related to the acquisition of the RSI Entities totaled $25.5 million. (3) Acquisitions (continued) Fair Value Measurement of Assets Acquired and Liabilities Assumed Described below are the methods used to determine the fair values of the significant assets acquired and liabilities assumed in the Freehold and RSI acquisitions: Cash and cash equivalents. The estimated fair values of cash and cash equivalents approximate their stated face amounts, as these financial instruments are either due on demand or have short-term maturities. Debt securities available for sale. The estimated fair values of the debt securities were calculated utilizing Level 2 inputs. The majority of the acquired securities were fixed income instruments that are not quoted on an exchange but are traded in active markets. The prices for these instruments are obtained through an independent pricing service when available, or dealer market participants with whom the Company has historically transacted with for both purchases and sales of securities. The prices are derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, and the bond's terms and conditions, among other things. Management reviewed the data and assumptions used in pricing securities by its third-party provider to ensure the highest level of significant inputs are derived from market observable data. Loans receivable. The acquired loan portfolio was segregated into pools for valuation purposes primarily based on loan type, non-accrual status, and credit risk rating. The estimated fair values were computed by discounting the expected cash flows from the respective pools. Cash flows were estimated by using valuation models that incorporated estimates of current key assumptions such as prepayment speeds, default rates, and loss severity rates. The process included: (1) projecting monthly principal and/or interest cash flows based on the contractual terms of the loans, including both maturity and contractual amortization; (2) adjusting projected cash flows for expected losses and prepayments, where appropriate; (3) developing a discount rate based on the relative risk of the cash flows, considering the loan type, liquidity risk, the maturity of the loans, servicing costs, and a required return on capital; and (4) discounting the projected cash flows to a present value, to arrive at the calculated value of the loans. The methods used to estimate the fair values of loans are extremely sensitive to the assumptions and estimates used. While management attempted to use assumptions and estimates that best reflected the acquired loan portfolios and current market conditions, a greater degree of subjectivity is inherent in the values than in those determined in active markets. Office properties and equipment, net. The fair value of land and buildings was estimated using current appraisals. Acquired equipment was not material. Buildings are amortized over their estimated useful lives. Equipment is amortized or depreciated over their estimated useful lives usually ranging from to fifteen years. Bank-owned life insurance. Bank-owned life insurance is accounted for using the cash surrender value method and is recorded at its net realizable value. Goodwill. Goodwill is not amortized for book purposes: however, it is reviewed at least annually for impairment and is not deductible for tax purposes. Core deposit intangibles. Core deposit intangibles ("CDI") are the measure of the value of non-maturity deposits in a business combination. The fair value of the CDI was calculated utilizing the cost savings approach, the expected cost savings attributable to the core deposits funding relative to an alternative source of funding, using a discounted cash flow present value methodology. Key inputs and assumptions utilized in the discounted cash flow present value methodology include core deposit balances and rates paid, the cost of an additional funding source, the aggregate life of deposits and truncation points, non-interest deposit costs, and the immediate deposit outflow assumption. Deposits. The fair values of deposit liabilities with no stated maturity (i.e., non-interest-bearing and interest-bearing demand deposit accounts, money market and savings and club deposits) are equal to the carrying amounts payable on demand. The fair value of certificates of deposit represents contractual cash flows, discounted to present value using interest rates currently offered on deposits with similar characteristics and remaining maturities. |

The amortized cost and fair value of debt securities available for sale at December 31, 2023, by contractual final maturity, is shown below. Expected maturities may differ from contractual maturities due to prepayment or early call options exercised by the issuer.
Mortgage-backed securities and collateralized mortgage obligations totaling $1.0 billion at amortized cost and $867.6 million at fair value, are not classified by maturity in the table above as their expected lives are likely to be shorter than the contractual maturity date due to principal prepayments. (4) Debt Securities Available for Sale (continued) During the year ended December 31, 2023, proceeds from the sale of debt securities available for sale totaled $277.0 million, resulting in no gross gains and $10.8 million of gross losses. There were no calls and $4,000 in maturities of debt securities available for sale during the year ended December 31, 2023. During the year ended December 31, 2022, proceeds from the sale of debt securities available for sale totaled $126.8 million, resulting in gross gains of $710,000 and $500,000 of gross losses.

(4) Debt Securities Available for Sale (continued) The number of securities in an unrealized loss position at December 31, 2023 totaled 329, compared with 455 at December 31, 2022. All temporarily impaired securities were investment grade as of December 31, 2023, except two corporate debt security positions totaling $8.1 million which are rated BB+. All temporarily impaired securities were investment grade at December 31, 2022. For available for sale securities, the Company assesses whether a loss is from credit or other factors and considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost, a credit loss would be recorded through an allowance for credit losses, limited by the amount that the fair value is less than the amortized cost basis. The following table presents the activity in the allowance for credit losses on debt securities available for sale for the years ended December 31, 2023 and 2022:
The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of debt securities available for sale.

For available for sale securities, the Company assesses whether a loss is from credit or other factors and considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost, a credit loss would be recorded through an allowance for credit losses, limited by the amount that the fair value is less than the amortized cost basis. The following table presents the activity in the allowance for credit losses on debt securities available for sale for the years ended December 31, 2023 and 2022:
The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of debt securities available for sale. Accrued interest receivable on debt securities available for sale is reported as a component of in the Consolidated Statements of Financial Condition, which totaled $3.7 million and $3.2 million at December 31, 2023 and 2022, respectively, and is excluded from the estimate of credit losses.

The amortized cost and fair value of debt securities held to maturity at December 31, 2023, by contractual final maturity, is shown below. Expected maturities may differ from contractual maturities due to prepayment or early call options exercised by the issuer.
Mortgage-backed securities and collateralized mortgage obligations totaling $351.3 million at amortized cost, and $313.2 million at fair value at December 31, 2023, are not classified by maturity in the table above as their expected lives are likely to be shorter than the contractual maturity date due to principal prepayments.

All of the mortgage-backed securities are issued by U.S. government agencies and are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses and, therefore, the expectation of non-payment is zero and the Company is not required to estimate an allowance for credit losses on these securities under the CECL standard. All these securities reflect a credit quality rating of AAA by Moody's Investors Service. The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of debt securities held to maturity. Accrued interest receivable on debt securities held to maturity is reported as a component of in the Consolidated Statements of Financial Condition, which totaled $997,000 and $1.0 million at December 31, 2023 and 2022, respectively, and is excluded from the estimate of credit losses.

| Receivable and Allowance for Credit Losses | Receivable and Allowance for Credit Losses Loans receivable at December 31, 2023 and 2022 are summarized as follows:
The Company had no loans held-for-sale at December 31, 2023 and 2022. During the year ended December 31, 2023, the Company sold $73.4 million, $21.4 million, $8.1 million, and $18.4 million of one-to-four family real estate loans and home equity loans, commercial real estate loans, construction loans, and SBA loans included in commercial business loans held-for sale, respectively, resulting in gross gains of $2.3 million and gross losses of $1.0 million. During the year ended December 31, 2022, the Company sold $2.7 million, $2.8 million, and $4.1 million of one-to-four family real estate loans, SBA loans included in commercial business loans, and construction loans held-for sale, respectively, resulting in gross gains of $242,000 and gross losses of $64,000. During the year ended December 31, 2021, the Company sold $18.5 million, $19.1 million, $6.4 million, and $258.1 million of one-to-four family real estate loans and home equity loans, commercial real estate loans, construction loans, and commercial business and SBA loans held-for-sale, respectively, resulting in gross gains of $8.6 million and gross losses of $24,000. During the year ended December 31, 2023, the Company purchased a $14.7 million commercial real estate participation loan from a third-party financial institution. During the year ended December 31, 2022 the Company purchased $8.3 million of one-to-four family real estate loans from third parties. During the year ended December 31, 2021 the Company purchased $11.8 million of one-to-four family real estate loans and $73.6 million of commercial real estate loans from third parties. At December 31, 2023 and 2022, commercial business loans included $809,000, and $1.6 million, respectively, in SBA Payroll Protection Program ("PPP") loans and net deferred fees related to these loans totaling $0 and $13,000, respectively. At December 31, 2023 and 2022, the carrying value of loans serviced by the Company for investors was $551.0 million and $497.1 million, respectively. These loans are not included in the Consolidated Statements of Financial Condition. Servicing income totaled $1.4 million, $1.3 million, and $1.5 million for the years ended December 31, 2023, 2022 and 2021. The Company has entered into guarantor swaps with Freddie Mac which results in improved liquidity. During the year ended December 31, 2023 and 2022, no loans were exchanged for Freddie Mac mortgage participation certificates. During the year ended December 31, 2021, the Company exchanged $99.6 million of loans for Freddie Mac mortgage participation certificates, resulting in gross gains of $2.3 million gross gains and no gross losses. The Company retained servicing of these loans. (7) Loans Receivable and Allowance for Credit Losses (continued) The Company has granted loans to certain officers and directors of the Company and its subsidiaries and to their associates. At December 31, 2023 and 2022, such loans totaled approximately $9.1 million and $9.3 million, respectively. During the years ended December 31, 2023, 2022 and 2021 Columbia Bank granted one new loan to a related party for $100,000, two new loans to a related party totaling $751,000, and one new loan to a related party for $522,700, respectively. These loans are performing in accordance with their original terms. The following tables summarize the aging of loans receivable by portfolio segment, including non-accrual loans and excluding PCD loans, at December 31, 2023 and 2022:
The Company considers a loan to be delinquent when we have not received a payment within 30 days of its contractual due date. Generally, a loan is designated as a non-accrual loan when the payment of interest is 90 days or more in arrears of its contractual due date. Non-accruing loans are returned to an accrual status after there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible. The Company identifies loans that may need to be charged-off as a loss, by reviewing all delinquent loans, classified loans and other loans that management may have concerns about collectability. At December 31, 2023 and 2022, non-accrual loans totaled $12.6 million and $6.7 million, respectively. Included in non-accrual loans at December 31, 2023 and 2022, are 10 and 7 loans totaling $1.6 million and $1.2 million which are less than 90 days in arrears. (7) Loans Receivable and Allowance for Credit Losses (continued) If non-accrual loans had performed in accordance with their original terms, interest income would have increased by $909,000, $392,000, and $190,000 for the years ended December 31, 2023, 2022 and 2021, respectively. The amount of cash basis interest income that was recognized on these loans during the years ended December 31, 2023, 2022 and 2021, was $358,000, $161,000, and $242,000, respectively. At December 31, 2023 and 2022, there were no loans past due 90 or more still accruing interest. Purchased credit impaired loans ("PCI") were loans acquired at a discount primarily due to deteriorated credit quality. These loans were initially recorded at fair value at acquisition, based upon the present value of expected future cash flows, with no related allowance for credit losses. In connection with the adoption of CECL on January 1, 2022, all loans considered PCI loans prior to that date were converted to purchase credit-deteriorated ("PCD") loans. Loans acquired in a business combination after January 1, 2022 are recorded in accordance with ASC Topic 326, which requires loans as of the acquisition date, that have experienced a more than insignificant deterioration in credit quality since origination to be classified as PCD loans. At December 31, 2023 and 2022, PCD loans acquired in the Stewardship Financial Corporation acquisition totaled $1.7 million and $2.0 million, respectively, PCD loans acquired in the Roselle Bank acquisition totaled $0 and $184,000, respectively, PCD loans acquired in the Freehold Bank acquisition totaled $2.8 million and $3.7 million, respectively, and PCD loans acquired in the RSI Bank acquisition totaled $10.6 million and $11.3 million, respectively. An initial allowance for credit losses of $633,000 was recorded through a gross-up adjustment to fair values of PCD loans related to the loans acquired in connection with the RSI Bank acquisition. We may obtain physical possession of real estate collateralizing a residential mortgage loan via foreclosure or through an in-substance repossession. At December 31, 2023 and 2022, the Company had no real estate owned. At December 31, 2023, we had one residential mortgage loan and one home equity loan with carrying values of $576,000 and $93,000, respectively, collateralized by residential real estate which were in the process of foreclosure. At December 31, 2022 we had two home equity loans with a total carrying value of $81,000, collateralized by residential real estate which were in the process of foreclosure. On January 1, 2022, the Company adopted CECL (ASC Topic 326), which replaced the historical incurred loss methodology with an expected loss methodology. The loan portfolio segmentation was expanded to seven portfolio segments taking into consideration common loan attributes and risk characteristics, as well as historical reporting metrics and data availability. The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of loans receivable. Accrued interest receivable on loans receivable is reported as a component of in the Consolidated Statements of Financial Condition, which totaled $32.9 million and $29.4 million at December 31, 2023 and 2022, respectively and is excluded from the estimate of credit losses. Refer to note 2, Summary of Significant Accounting Policies for additional information on the adoption of Topic 326 and CECL methodology. The allowance for credit losses on loans ("ACL") is established through the provision for credit losses that are charged to income, which is based upon an evaluation of estimated losses in the current loan portfolio, including the evaluation of individually analyzed loans. Charge-offs against the ACL are taken on loans where management determines that the collection of loan principal and interest is unlikely. Recoveries made on loans that have been charged-off are credited to the ACL. Although we believe we have established and maintained the ACL on loans at appropriate levels, changes in reserves may be necessary if actual economic and other conditions differ substantially from the forecast used in estimating the ACL. (7) Loans Receivable and Allowance for Credit Losses (continued) The following tables summarize loans receivable (including PCD loans) and allowance for credit losses by portfolio segment and impairment method at December 31, 2023 and 2022:
(7) Loans Receivable and Allowance for Credit Losses (continued)
On January 1, 2023, the Company adopted ASU 2022-02, Financial Instruments-Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures, which eliminated the accounting guidance for troubled debt restructurings (“TDRs”) while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. This guidance was applied on a prospective basis.

The categorization of loans into risk categories is based upon relevant information about the borrower's ability to service their debt. The Company utilizes an eight-point risk rating system to summarize its loan portfolio into categories with similar risk characteristics. Loans deemed to be “acceptable quality” are rated 1 through 4 (Pass), with a rating of 1 established for loans with minimal risk. Loans that are deemed to be of “questionable quality” are rated 5 (Special Mention) or 6 (Substandard). Loans with adverse classifications are rated 7 (Doubtful) or 8 (Loss). The risk ratings are also confirmed through periodic loan review examinations which are currently performed by both an independent third-party and the Company's credit risk review department. The Company requires an annual review be performed above certain dollar thresholds, depending on loan type, to help determine the appropriate risk ratings. Results from examinations are presented to the Audit Committee of the Board of Directors.

| Leases | Leases The Company leases real estate property for branches and office space. At December 31, 2023 and 2022, all of the Company's leases are classified as operating leases. The Company determines if an arrangement is a lease at inception. Topic 842 requires lessees to recognize a right-of-use asset and a lease liability, measured at the present value of the future minimum lease payments, at the lease commencement date. The calculated amount of the right-of-use asset and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of minimum lease payments. At December 31, 2023 and 2022, the weighted average remaining lease term for operating leases was 5.9 years and 6.5 years, respectively, and the weighted average discount rate used in the measurement of operating lease liabilities was 2.70% and 2.35%, respectively. The Company elected to account for the lease and non-lease components separately since such amounts are readily determinable under the Company's lease contracts. Operating lease expense is recognized on a straight-line basis over the lease term, while variable lease payments are recognized as incurred. Variable lease payments include common area maintenance charges, real estate taxes, repairs and maintenance costs and utilities. Operating and variable lease expenses are recorded in occupancy expense in the Consolidated Statements of Income. During both the years ended December 31, 2023 and 2022, operating and variable lease expenses totaled approximately $2.7 million. There were no sale and leaseback transactions, leveraged leases or lease transactions with related parties during the years ended December 31, 2023 and 2022. At December 31, 2023, the Company had no leases which had not yet commenced. The following table summarizes lease payment obligations for each of the next five years and thereafter as follows:

| Stockholders' Equity | Stockholders' Equity Regulatory Capital The Company and its subsidiary banks (Columbia Bank and Freehold Bank) are subject to various regulatory capital requirements administered by the federal banking regulators, including a risk-based capital measure. The Federal Reserve establishes capital requirements, including well capitalized standards, for the consolidated financial holding company, and the Office of the Comptroller of the Currency (the "OCC") has similar requirements for the Company's subsidiary banks. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's Consolidated Statements of Financial Condition. Federal regulators require federally insured depository institutions to meet several minimum capital standards: (1) total capital to risk-weighted assets of 8.0%; (2) tier 1 capital to risk-weighted assets of 6.0%; (3) common equity tier 1 capital to risk-weighted assets of 4.5%; and (4) tier 1 capital to adjusted total assets of 4.0%. In addition to establishing the minimum regulatory capital requirements, the regulations limit capital distributions and certain discretionary bonus payments to management if the institution does not hold a "capital conservation buffer" consisting of 2.5% of common equity tier 1 capital to risk-weighted assets above the amount necessary to meet its minimum risk-based capital requirements. The regulators established a framework for the classification of savings institutions into five categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. Generally, an institution is considered well capitalized if it has: a total capital to risk-weighted assets ratio of at least 10.0%, a tier 1 capital to risk-weighted assets ratio of at least 8.0%, a common tier 1 capital to risk-weighted assets ratio of at least 6.5%, and a tier 1 capital to adjusted total assets ratio of at least 5.0%. As of December 31, 2023 and 2022, each of the Company and the Columbia Bank and Freehold Bank exceeded all capital adequacy requirements to which it is subject. Based upon most recent notification from federal banking regulators, the banks were categorized as well capitalized under the regulatory framework for prompt corrective action. There are no conditions existing or events which have occurred since notification that management believes have changed the Bank's category. The following tables presents the Company's, Columbia Bank's and Freehold Bank's actual capital amounts and ratios at December 31, 2023 and 2022 compared to the Federal Reserve Bank minimum capital adequacy requirements and the Federal Reserve Bank requirements for classification as a well-capitalized institution: (13) Stockholders' Equity (continued) Regulatory Capital (continued)

| Employee Benefit Plans | Employee Benefit Plans Pension Plan, Retirement Income Maintenance Plan (the "RIM Plan"), Post-retirement Plan, Split-Dollar Life Insurance Plans The Company maintains a single employer, tax-qualified defined benefit pension plan (the "Pension Plan") which covers full-time employees that satisfy the Pension Plan's eligibility requirements. The benefits are based on years of service and the employee's average compensation for the highest consecutive years of employment. Effective October 1, 2018, newly hired employees are not eligible to participate in Columbia Bank's Pension Plan as the plan has been closed to new employees as of that date. The Company's policy is to fund at least the minimum contribution required by the Employee Retirement Income Security Act of 1974. GAAP requires an employer to: (a) recognize in its statement of financial position the over-funded or under-funded status of a defined benefit post-retirement plan measured as the difference between the fair value of plan assets and the benefit obligation; (b) measure a plan’s assets and its obligations that determine its funded status at the end of the employer’s fiscal year (with limited exceptions); and (c) recognize as a component of other comprehensive income (loss), net of tax, the actuarial gains and losses and the prior service costs and credits that arise during the period. The assets of the plan are primarily invested in fixed income and equity funds. The Company also maintains a Retirement Income Maintenance Plan (the "RIM" Plan), which is a non-qualified defined benefit plan which provides benefits to all employees of the Company if their benefits under the Pension Plan are limited by Internal Revenue Code 415 and 401(a)(17). In addition, the Company provides certain health care and life insurance benefits to eligible retired employees under a Post-retirement Plan. The Company accrues the cost of retiree health care and other benefits during the employees’ period of active service. Effective January 1, 2019, the Post-retirement Plan has been closed to new hires. The Company also provides life insurance benefits to eligible employees under an endorsement split-dollar life insurance program. The Company recognizes a liability for future benefits applicable to endorsement split-dollar life insurance arrangements that provide death benefits post-retirement. Through its mergers, the Company recognized additional liability for future benefits applicable to endorsement split-dollar life insurance arrangements that provide death benefits post-retirement under those respective Bank's program. (14) Employee Benefit Plans (continued) Pension Plan, Retirement Income Maintenance Plan (the "RIM Plan") Post-retirement Plan, Split-Dollar Life Insurance Plans (cont'd) The following table sets forth information regarding the Pension Plan, RIM, Post-retirement Plan and Split-Dollar Life Insurance Plans at December 31, 2023 and 2022:
At December 31, 2023 and 2022, the unfunded liability for the RIM Plan and Post-retirement Plan of $13.6 million and $21.1 million, and $12.6 million and $19.8 million, respectively, were included in other liabilities in the Consolidated Statements of Financial Condition, and the over-funded pension benefits associated with the Pension Plan totaling $197.7 million and $181.6 million respectively, were included in other assets in the Consolidated Statements of Financial Condition. The actuarial losses related to the change in benefit obligations for the year ended December 31, 2023 resulted from a decrease in the discount rates and the update of census data, while the significant increase in actuarial gains related to the change in benefit obligations for the year ended December 31, 2022 resulted from a substantial increase in the discount rates. (14) Employee Benefit Plans (continued) Pension Plan, Retirement Income Maintenance Plan (the "RIM Plan") Post-retirement Plan, Split-Dollar Life Insurance Plans (cont'd) The components of accumulated other comprehensive income related to the Pension Plan, RIM Plan, and Post-retirement Plan and Split-Dollar Life Insurance Plan on a pre-tax basis, at December 31, 2023, 2022, and 2021, are summarized in the following table:
Net periodic (income) benefit cost for the Pension Plan, RIM Plan, Post-retirement Plan and Split-Dollar Life Insurance plan benefits for the years ended December 31, 2023 and 2022, and 2021, includes the following components:
(14) Employee Benefit Plans (continued) Pension Plan, Retirement Income Maintenance Plan (the "RIM Plan") Post-retirement Plan, Split-Dollar Life Insurance Plans (cont'd)
There are no contributions expected to made to the Pension Plan during the year ended December 31, 2024. (14) Employee Benefit Plans (continued) Pension Plan, Retirement Income Maintenance Plan (the "RIM Plan") Post-retirement Plan, Split-Dollar Life Insurance Plans (cont'd) The weighted average actuarial assumptions used in the plan determinations at and for the years ended December 31, 2023, 2022, and 2021 were as follows:
(14) Employee Benefit Plans (continued) Pension Plan, Retirement Income Maintenance Plan (the "RIM Plan") Post-retirement Plan, Split-Dollar Life Insurance Plans (cont'd)
For measurement purposes in the Post-retirement Plan, the fiscal year 2023 weighted average health care cost trend rate assumption was 7.60% for pre-65 year olds and 7.85% for post-65 year olds in 2023, decreasing ratably to 4.50% through 2033. The Company provides its actuaries with certain rate assumptions used in measuring the respective benefit obligations. The most significant of these is the discount rate used to calculate the period-end present value of the benefit obligations, and the expense to be included in the following year's consolidated financial statements. A lower discount rate will result in a higher benefit obligation and expense, while a higher discount rate will result in a lower benefit obligation and expense. The discount rate assumption was determined based on a cash flow-yield curve model specific to the Company's pension and post-retirement plans. The Company compares this rate to certain market indices, such as long-term treasury bonds, or pension liability indices, for reasonableness. The Company's expected return on plan assets assumption is based on historical investment return rate experience, evaluation of input from the trustee managing the pension plan's assets and Columbia Bank's Pension Committee which has responsibility for managing these assets. The expected return on pension plan assets is also impacted by the target allocation of assets, which is based on the Company's goal of earning the highest rate of return while maintaining risk at acceptable levels. (14) Employee Benefit Plans (continued) Pension Plan, Retirement Income Maintenance Plan (the "RIM Plan") Post-retirement Plan, Split-Dollar Life Insurance Plans (cont'd) Estimated future benefit payments, which reflect expected future service, as appropriate for the next five years and thereafter are as follows:
The weighted average asset allocation of pension assets at December 31, 2023 and 2022 were as follows:
Management, under the direction of Columbia Bank's Pension Committee, strives to have pension assets sufficiently diversified so that adverse or unexpected results from one security class will not have a significant detrimental impact on the entire portfolio. The 2023 target allocation of assets and acceptable ranges around the targets are as follows:
Columbia Bank's Pension Committee engages an investment management advisory firm to regularly monitor the performance of the asset managers and ensure they are within compliance with policy. The maximum and minimum of the range for each class is based on the fair value of the assets in the fund. If changes in fair value should lead to allocations outside these boundaries, management shall adjust exposure back to the established guidelines within 90 days or reevaluate the guidelines. (14) Employee Benefit Plans (continued) Pension Plan, Retirement Income Maintenance Plan (the "RIM Plan") Post-retirement Plan, Split-Dollar Life Insurance Plans (cont'd) The following tables present the assets that are measured at fair value on a recurring basis by level within the U.S. GAAP fair value hierarchy as reported on the Statements of Net Assets Available for Plan Benefits at December 31, 2023 and 2022, respectively. A financial instrument's level within the fair value hierarchy's is based on the lowest level of input that is significant to the fair value measurement.

(14) Employee Benefit Plans (continued) Pension Plan and Post-retirement Plan Acquired-RSI Through the acquisition of the RSI Entities on May 1, 2022, the Company acquired a funded pension plan and a non-funded post-retirement plan. The benefits are based on years of service and the employee’s compensation, as defined. The Plan was amended effective March 31, 2011, to freeze the Plan so that no employee shall commence or recommence participation in the Plan, that there shall be no further benefit accruals under the Plan, and that compensation received after the effective date shall not be recognized for any purpose under the Plan. Effective September 30, 2023, the RSI Bank Retirement Plan was merged, and all assets were transferred into the Columbia Bank Pension Plan. The defined benefit post-retirement healthcare plan covers substantially all retirees and employees. The following table sets forth information regarding the Pension Plan and Post-retirement Plan at December 31, 2023 and 2022:
At December 31, 2023 and 2022, the unfunded liability for the Post-retirement Plan of $2.5 million and $2.0 million, respectively, was included in other liabilities in the Consolidated Statements of Financial Condition, and the over-funded pension benefits associated with the Pension Plan at December 31, 2022, totaling $1.0 million, was included in other assets in the Consolidated Statements of Financial Condition.

The ESOP used $45.4 million in proceeds from a 20 years term loan obtained from the Company to purchase 4,542,855 shares of Company common stock. The term loan principal is payable in installments through April 2038. Interest on the term loan is fixed at a rate of 4.75%. Each year, Columbia Bank makes discretionary contributions to the ESOP, which are equal to principal and interest payments required on the term loan. Shares purchased with the loan proceeds were initially pledged as collateral for the term loan and is held in a suspense account for future allocation among participants. Contributions to the ESOP and shares released form the suspense account are allocated among the participants on the basis of compensation, as described by the ESOP in the year of allocation. The ESOP shares pledged as collateral are reported as unearned ESOP shares in the Consolidated Statements of Financial Condition. As shares are committed to be released from collateral, the Company reports compensation expense equal to the average market price of the shares during the year, and the shares become outstanding for basic net income per common share computations. ESOP compensation expense for the years ended December 31, 2023, 2022, and 2021 was $4.1 million, $4.9 million and $4.1 million, respectively. The ESOP shares were as follows:

The expected future compensation expense related to the 435,541 non-vested restricted shares outstanding at December 31, 2023 is approximately $5.0 million over a weighted average period of 1.5 years. The following is a summary of the Company's restricted stock activity during the years ended December 31, 2023 and 2022:
(14) Employee Benefit Plans (continued) Stock Based Compensation (continued) On March 21, 2022, options to purchase 130,951 shares of Company common stock were awarded with a grant date fair value of $6.51 per option. Stock options granted under the 2019 Plan vest in equal installments over the service period of three years beginning one year from the date of grant. These stock options were granted at an exercise price of $21.79, which represents the fair value of the Company's common stock price on the grant date based on the closing market price and have an expiration period of 10 years. The fair value of stock options granted was estimated utilizing the Black-Scholes option pricing model using the following assumptions: expected life of 6 years, risk-free rate of return of 2.34%, volatility of 25.31%, and a dividend yield of 0.00%. On October 31, 2022, options to purchase 173,766 shares of Company common stock were awarded with a grant date fair value of $7.22 per option. Stock options granted under the 2019 Plan vest in equal installments over the service period of three years beginning one year from the date of grant. These stock options were granted at an exercise price of $20.54, which represents the fair value of the Company's common stock price on the grant date based on the closing market price and have an expiration period of 10 years. The fair value of stock options granted was estimated utilizing the Black-Scholes option pricing model using the following assumptions: expected life of 6 years, risk-free rate of return of 4.19%, volatility of 26.25%, and a dividend yield of 0.00%. On December 19, 2022, options to purchase 58,912 shares of Company common stock were awarded with a grant date fair value of $6.79 per option. Stock options granted under the 2019 Plan generally vest in equal installments over the service period of one year beginning one year from the date of grant. These stock options were granted at an exercise price of $21.07, which represents the fair value of the Company's common stock price on the grant date based on the closing market price and have an expiration period of approximately 10 years. The fair value of stock options granted was estimated utilizing the Black-Scholes option pricing model using the following assumptions: expected life of 5.5 years, risk-free rate of return of 3.71%, volatility of 26.11%, and a dividend yield of 0.00%. On May 1, 2023, options to purchase 286,016 shares of Company common stock were awarded with a grant date fair value of $5.48 per option. Stock options granted under the 2019 Plan generally vest in equal installments over the service period of three years beginning one year from the date of grant. These stock options were granted at an exercise price of $15.94, which represents the fair value of the Company's common stock price on the grant date based on the closing market price and have an expiration period of approximately 10 years. The fair value of stock options granted was estimated utilizing the Black-Scholes option pricing model using the following assumptions: expected life of 6 years risk-free rate of return of 3.60%, volatility of 27.07%, and a dividend yield of 0.00%. The expected life of the options represents the period of time that stock options are expected to be outstanding and is estimated using the simplified approach, which assumes that all outstanding options will be exercised at the midpoint of the vesting date and full contractual term. The risk-free rate of return is based on the rates on the grant date of a U.S. Treasury Note with a term equal to the expected option life. Since the Company recently converted to a public company and does not have sufficient historical price data, the expected volatility is based on the historical daily stock prices of Company stock plus a peer group of similar entities based on factors such as industry, stage of life cycle, size and financial leverage. The Company has not paid any cash dividends on its common stock. Management recognizes expense for the fair value of these awards on a straight-line basis over the requisite service period. During the years ended December 31, 2023, 2022, and 2021, approximately $3.9 million, $3.2 million, and $3.2 million, respectively, in expense was recognized in regard to these awards. The expected future compensation expense related to the 1,056,804 non-vested options outstanding at December 31, 2023 is $3.5 million over a weighted average period of 1.5 years. (14) Employee Benefit Plans (continued) Stock Based Compensation (continued) The following is a summary of the Company's option activity during the years ended December 31, 2023 and 2022:
The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value, the difference between the Company's closing stock price on the last trading day of the period and the exercise price, multiplied by the number of in-the-money options. During the years ended December 31, 2023, 2022 and 2021, the aggregate intrinsic value of options exercised was approximately $154,000, $1.8 million, and $60,000, respectively.

The Company reported deferred tax (benefit) expense of $(11.5) million, $53.4 million, and $8.0 million for the years ended December 31, 2023, 2022, and 2021, respectively, related to the unrealized gains (losses) on securities available for sale, which is reported in accumulated other comprehensive income (loss), net of tax. Additionally, the Company recorded a deferred tax (benefit) expense of $218,000, $749,000, and $1.1 million, respectively, related to the reclassification adjustment of actuarial net (loss) gain on employee benefit obligations, which is reported in accumulated other comprehensive income, net of tax. Deferred tax assets and/or liabilities for the years ended December 31, 2022 and 2021, also includes $9.6 million, and $1.5 million respectively, recorded as a result of purchase accounting related to the RSI and Freehold acquisitions, respectively. Deferred tax assets for the year ended December 31, 2022 also includes $2.4 million related to the adoption of CECL on January 1, 2022. A reconciliation between the amount of reported total income tax expense and the amount computed by multiplying the applicable statutory federal income tax rate of 21% is as follows:
(15) Income Taxes (continued) The net deferred tax asset/liability is included in other assets/liabilities in the Consolidated Statements of Financial Condition. The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2023 and 2022 are as follows:
Retained earnings at December 31, 2023 and 2022 includes approximately $21.5 million for which no provision for income tax has been made. This amount represents an allocation of income to bad debt deductions for tax purposes only. Events that would result in taxation of these reserves include the failure to qualify as a bank for tax purposes, distributions in complete or partial liquidation, stock redemptions and excess distributions to stockholders. (15) Income Taxes (continued) Management believes that not all existing net deductible temporary differences that comprise the net deferred tax asset will reverse during periods in which the Company generates sufficient net taxable income. Accordingly, management has established a valuation allowance. Significant changes in the Company's operations and or economic conditions could affect the benefits of the recognized net deferred tax assets. Management believes, based on current facts, that it is more likely than not that there will be sufficient taxable income in future years to realize federal deferred tax assets. Historically, the Company believed that it was more likely than not that the benefits from certain New Jersey net operating loss carryforwards and tax credits would not be realized, and therefore, a valuation allowance was established for the portion of the state tax benefit that would not be realized. On July 3, 2023, the State of New Jersey enacted comprehensive tax legislation which changed net operating loss conversion carryovers, allowing members of a unitary group to utilize pre-conversion state net operating losses. As a result of this legislation, management believes substantially all New Jersey net operating losses will be available to offset future taxable income, and therefore, the Company reduced its valuation allowance related to these state attributes during the year ended December 31, 2023. At December 31, 2023 and 2022, the Company's valuation allowance totaled $26,000 and $2.0 million, respectively. Based upon projections of future taxable income, management believes it is more likely than not the Company will realize the remaining deferred tax assets. The Company had federal net operating losses from the acquisition of Roselle of approximately $5.6 million and $7.8 million at December 31, 2023 and 2022, respectively. Roselle net operating losses are subject to a 20 year carryforward. The Company also had federal net operating losses from the acquisition of RSI of approximately $5.2 million and $8.6 million at December 31, 2023 and 2022, respectively. RSI net operating losses have an indefinite carryover subject to an 80% taxable income utilization and are subject to an annual limitation under Code Section 382. The Roselle net operating losses are subject to an annual limitation under Code Section 382 and will begin to expire in 2036 if not used. The Company had New Jersey net operating loss carryforwards of $186.0 million and $147.0 million, respectively, at December 31, 2023 and 2022. If not utilized, these carryforwards will expire periodically through 2042. At both December 31, 2023 and 2022, the Company had approximately $2.2 million of New Jersey AMA Tax Credits. These credits do not expire. The Company files income tax returns in the United States federal jurisdiction and in the states of New Jersey, New York, and Pennsylvania. At December 31, 2023, the Company is no longer subject to federal income tax examination for the years prior to 2020. Columbia Bank MHC and its subsidiaries' New York City returns are currently under audit for the tax years 2016 and 2017. The Company is open for examination by the State of New Jersey for years after 2019 and by the State of Pennsylvania for years after 2020.

| Commitments and Contingencies Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Financial Transactions with Off-Balance-Sheet Risk and Concentrations of Credit Risk | Financial Transactions with Off-Balance-Sheet Risk and Concentrations of Credit Risk The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business in order to meet the financing needs of its customers. These financial instruments consist of commitments to extend credit and involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the Consolidated Statements of Financial Condition. At December 31, 2023 and 2022, the following commitments existed which are not reflected in the Consolidated Statements of Financial Condition:
Unused lines of credit consisting of home equity lines, and undisbursed business and construction lines totaled approximately $1.3 billion and $1.2 billion as of December 31, 2023 and 2022, respectively. Amounts drawn on the unused lines of credit are predominantly assessed interest at rates that fluctuate with the base rate. The Company uses the same credit policies and collateral requirements in making commitments and conditional obligations as it does for on-balance-sheet loans. Commitments to extend credit are agreements to lend to customers as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management's credit evaluation of the borrower. The Company principally grants residential real estate loans, multifamily real estate loans, commercial real estate loans, construction loans, commercial business loans, home equity loans and advances and other consumer loans to borrowers primarily throughout New Jersey, New York and Pennsylvania, and to a much lesser extent in a few other east coast states. Its borrowers' abilities to repay their obligations are dependent upon various factors, including the borrowers' income and net worth, cash flows generated by the underlying collateral, if any, or from business operations, value of the underlying collateral and priority of the Company's lien on the property. These factors are dependent on various economic conditions and circumstances beyond the Company's control, and as a result, the Company is subject to the risk of loss. The Company believes that its lending policies and procedures adequately minimize the potential exposure to such risks and adequate provisions for loan losses are provided for all probable and estimable losses. In the normal course of business, the Company sells residential real estate loans to third parties. These loan sales are subject to customary representations and warranties. In the event that the Company is found to be in breach of these representations and warranties, it may be obligated to repurchase certain of these loans. The Company has entered into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company's derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company's known or expected cash receipts and its known or expected cash payments principally related to the Company's borrowings. These derivatives were used to hedge the variability in cash flows associated with certain short-term funding transactions. The fair value of the derivatives as of December 31, 2023 and 2022 was a net liability of $6.1 million and $684,000, respectively, net of accrued interest and variation margin posted in accordance with the Chicago Mercantile Exchange. (16) Financial Transactions with Off-Balance-Sheet Risk and Concentrations of Credit Risk (continued) In connection with its mortgage banking activities, at December 31, 2023 and 2022 the Company had no commitments to sell loans, and no commitments classified as held-for-sale. The Company is also a party to standby letters of credit, which are conditional commitments issued to guarantee the performance of a customer to a third party. These guarantees generally extend for a term of up to one year and may be secured or unsecured. The balance of standby letters of credit totaled $33.1 million and $20.4 million at December 31, 2023 and 2022, respectively. The FHLB has issued irrevocable standby letters of credits totaling $575.0 million at December 31, 2023 for purposes of collateralizing Columbia Bank's New Jersey public funds on deposit. These letters are renewable on an annual basis and are securitized by loans and securities. The FHLB also has issued an irrevocable standby letter of credit totaling $600,000 at both December 31, 2023 and 2022, respectively, for the purposes of collateralizing Freehold Bank's retention of New Jersey public funds on deposit as required by the New Jersey Governmental Unit Deposit Protection Act. This letter is renewable on an annual basis and is securitized by Freehold Bank's available borrowing line at the FHLB. The Company and its subsidiaries are also party to litigation which arises primarily in the ordinary course of business. In the opinion of management, these legal actions and claims are not expected to have a material adverse impact on the consolidated financial position of the Company. The Company is required to include unfunded commitments that are expected to be funded in the future within the allowance calculation, other than those that are unconditionally cancellable. To arrive at that reserve, the reserve percentage for each applicable segment is applied to the unused portion of the expected commitment balance and is multiplied by the expected funding rate. To determine the expected funding rate, the Company uses a historical utilization rate for each segment. The allowance for credit losses on off-balance-sheet exposures is reported in other liabilities in the Consolidated Statements of Financial Condition. The liability represents an estimate of expected credit losses arising from off-balance-sheet exposures such as unfunded commitments. At December 31, 2023and 2022, the balance of the allowance for credit losses on unfunded commitments, included in other liabilities, totaled $5.5 million and $7.0 million, respectively. The Company recorded a reversal of provision for credit losses on unfunded commitments, included in other non-interest expense in the Consolidated Statements of Income, of $1.5 million and $1.2 million for the years ended December 31, 2023and 2022, respectively. The following table presents the activity in the allowance for credit losses on off-balance-sheet exposures for years ended December 31, 2023and 2022:

| Fair Value Measurements | Fair Value Measurements The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. Where quoted market values in an active market are not readily available, the Company utilizes various valuation techniques to estimate fair value. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure the fair values: Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access on the measurement date. Level 2: Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar instruments in markets that are active or not active, or inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. Level 3: Prices or valuation techniques that require unobservable inputs that are both significant to the fair value measurement and unobservable (i.e., supported by minimal or no market activity). Valuation techniques include the use of option pricing models, discounted cash flow models and similar techniques. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Assets and Liabilities Measured at Fair Value on a Recurring Basis The methods described below were used to measure fair value of financial instruments as reflected in the tables below on a recurring basis as of December 31, 2023 and 2022. Debt Securities Available for Sale, at Fair Value For debt securities available for sale, fair value was estimated using a market approach. The majority of these securities are fixed income instruments that are not quoted on an exchange but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations, matrix pricing and discounted cash flow pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to a benchmark or to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. Discounted cash flows, a Level 3 input, is estimated by discounting the expected future cash flows using the current rates for securities with similar credit ratings and similar remaining maturities. As the Company is responsible for the determination of fair value, it performs quarterly analysis on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to assess the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in an adjustment in the prices obtained from the pricing service. The Company may hold debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. The Company classifies the estimated fair value of its loan portfolio as Level 3. Equity Securities, at Fair Value The Company holds equity securities that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. A trust preferred security that is not traded in an active market and Federal Home Loan Mortgage Corporation ("FHLMC") and Federal National Mortgage Association ("FNMA") preferred stock, are considered Level 2 instruments. In addition, Level 2 instruments include Atlantic Community Bankers Bank ("ACBB") stock, which is based on redemption at par value and can only be sold to the issuing ACBB or another institution that holds ACBB stock. (17) Fair Value Measurements (continued) Derivatives The Company records all derivatives included in and in the Consolidated Statements of Financial Condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. See note 21 for disclosures related to the accounting treatment for derivatives. The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs. The following tables present the assets and liabilities reported in the Consolidated Statements of Financial Condition at their fair values as of December 31, 2023 and 2022, by level within the fair value hierarchy:
(17) Fair Value Measurements (continued)
The table below provides activity of assets reported as Level 3 for the years ended December 31, 2023 and 2022:
The fair value of investments placed in Level 3 is estimated by discounting the expected future cash flows using reasonably available current rates for comparable new issue securities with similar structure, including original maturity, call date, and assumptions about risk. Discounted cash flow estimated valuations are subsequently validated against comparable structures as an approximation of value. Expected cash flows were projected based on contractual cash flows. There were no transfers to Level 3 assets during the year ended December 31, 2023. Two private placement corporate debt securities classified as available for sale and four private placement municipal obligations classified as available for sale were transferred from Level 2 to Level 3 during the year ended December 31, 2022. (17) Fair Value Measurements (continued) Private placement debt security cash flows were discounted to a market yield of 12.00% (weighted average is 12.00%), and the cash flows for private placement municipal obligations were discounted to a market yield ranging from 3.40% to 3.99% (weighted average is 3.69%). The period end valuations were support by an analysis prepared by an independent third party market participant and approved by management. Assets Measured at Fair Value on a Non-Recurring Basis The valuation techniques described below were used to estimate fair value of financial instruments measured on a non-recurring basis as of December 31, 2023 and 2022. Individually Analyzed Collateral Dependent Loans/Impaired Loans The fair value of collateral dependent loans that are individually analyzed or were previously deemed impaired is measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral if the loan is collateral dependent. For individually analyzed loans measured for impairment based on the fair value of the underlying collateral, fair value was estimated using a market approach. The Company measures the fair value of collateral underlying impaired loans primarily through obtaining independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraisers’ market knowledge and experience, as well as adjustments for estimated costs to sell between 6% and 8%. For non-collateral dependent loans, management estimates fair value using discounted cash flows based on inputs that are largely unobservable. The Company classifies these loans as Level 3 within the fair value hierarchy. Mortgage Servicing Rights, Net ("MSR"s") Mortgage servicing rights are carried at the lower of cost or estimated fair value. The estimated fair value of MSRs is obtained through an analysis of future cash flows, incorporating assumptions that market participants would use in determining fair value including market discount rates, prepayments speeds, servicing income, servicing costs, default rates and other market driven data, including the market's perception of future interest rate movements. The prepayment speed and the discount rate are considered two of the most significant inputs in the model. A significant degree of judgment is involved in valuing the mortgage servicing rights using Level 3 inputs. The use of different assumptions could have a significant effect on this fair value estimate. The following tables present the assets and liabilities reported in the Consolidated Statements of Financial Condition at their fair values on a non-recurring basis at December 31, 2023 and 2022, by level within the fair value hierarchy:
(17) Fair Value Measurements (continued)
The following table presents information for Level 3 assets measured at fair value on a non-recurring basis at December 31, 2023 and 2022:
Other Fair Value Disclosures The Company is required to disclose estimated fair value of financial instruments, both assets and liabilities on and off the balance sheet, for which it is practicable to estimate fair value. A description of the valuation methodologies used for those assets and liabilities not recorded at fair value on a recurring or non-recurring basis are set forth below. Cash and Cash Equivalents For cash and due from banks, federal funds sold and short-term investments, the carrying amount approximates fair value due to their nature and short-term maturities. (17) Fair Value Measurements (continued) Debt Securities Held to Maturity For debt securities held to maturity, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to benchmark or to compare securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As the Company is responsible for the determination of fair value, it performs quarterly analysis on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to assess the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in an adjustment in the prices obtained from the pricing service. The Company also holds debt instruments issued by the U.S. government and U.S. government sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs within the fair value hierarchy. Federal Home Loan Bank Stock ("FHLB") The fair value of FHLB stock is based on redemption at par value and can only be sold to the issuing FHLB, to other FHLBs, or to other member banks. As such, the Company's FHLB stock is recorded at cost, or par value, and is evaluated for impairment each reporting period by considering the ultimate recoverability of the investment rather than temporary declines in value. The Company classifies the estimated fair value as Level 2 within the fair value hierarchy. Loans Receivable Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial mortgage, residential mortgage, commercial, construction, and consumer and other. Each loan category is further segmented into fixed and adjustable rate interest terms and into performing and non-performing categories. The fair value of performing loans was estimated using a combination of techniques, including a discounted cash flow model that utilizes a discount rate that reflects the Company's current pricing for loans with similar characteristics and remaining maturity, adjusted by an amount for estimated credit losses inherent in the portfolio at the balance sheet date. The rates take into account the expected yield curve, as well as an adjustment for prepayment risk, when applicable. The Company classifies the estimated fair value of its loan portfolio as Level 3. The fair value for significant non-performing loans was based on recent external appraisals of collateral securing such loans, adjusted for the timing of anticipated cash flows. The Company classifies the estimated fair value of its non-performing loan portfolio as Level 3. Deposits The fair value of deposits with no stated maturity, such as demand, money market, and savings and club deposits are payable on demand at each reporting date and classified as Level 2. The estimated fair value of certificates of deposit was based on the discounted value of contractual cash flows. The discount rate was estimated using the Company’s current rates offered for deposits with similar remaining maturities. The Company classifies the estimated fair value of its certificates of deposit portfolio as Level 2. Borrowings The fair value of borrowings was estimated by discounting future cash flows using rates available for debt with similar terms and maturities and is classified by the Company as Level 2 within the fair value hierarchy. (17) Fair Value Measurements (continued) Commitments to Extend Credit and Letters of Credit The fair value of commitments to extend credit and letters of credit was estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counter-parties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value estimates of commitments to extend credit and letters of credit are deemed immaterial. The following tables present the assets and liabilities reported in the Consolidated Statements of Financial Condition at their fair values as of December 31, 2023 and 2022:
(17) Fair Value Measurements (continued)
Limitations Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because limited markets exist for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Other significant assets and liabilities that are not considered financial assets or liabilities include goodwill and intangible assets, deferred tax assets and liabilities, office properties and equipment, and bank-owned life insurance.

| Earnings per Share | Earnings per Share Basic earnings per share ("EPS") is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. For purposes of calculating basic EPS, weighted average common shares outstanding excludes treasury stock, unallocated employee stock ownership plan shares that have not been committed for release and deferred compensation obligations required to be settled in shares of Company stock. Diluted EPS is computed using the same method as basic EPS and reflects the potential dilution which could occur if stock options and unvested shares were exercised and converted into common stock. The potentially diluted shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method. The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share calculations for the years ended December 31, 2023, 2022, and 2021:
For the years ended December 31, 2023, 2022, and 2021, the average number of stock options which could potentially dilute basic earnings per share in the future that were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive totaled 704,526, 129,049, and 3,726,249 respectively.

| Derivatives and Hedging Activities | Derivatives and Hedging Activities The Company uses derivative financial instruments as components of its market risk management, principally to manage interest rate risk. Certain derivatives are entered into in connection with transactions with commercial customers. Derivatives are not used for speculative purposes. All derivatives are recognized as either assets or liabilities in the Consolidated Statements of Financial Condition, reported at fair value and presented on a gross basis. Until a derivative is settled, a favorable change in fair value results in an unrealized gain that is recognized as an asset, while an unfavorable change in fair value results in an unrealized loss that is recognized as a liability. The Company generally applies hedge accounting to its derivatives used for market risk management purposes. Hedge accounting is permitted only if specific criteria are met, including a requirement that a highly effective relationship exists between the derivative instrument and the hedged item, both at inception of the hedge and on an ongoing basis. Changes in the fair value of effective fair value hedges are recognized in current earnings (with the change in fair value of the hedged asset or liability also recognized in earnings). Changes in the fair value of effective cash flow hedges are recognized in other comprehensive income (loss) until earnings are affected by the variability in cash flows of the designated hedged item. Ineffective portions of hedge results are recognized in current earnings. Changes in the fair value of derivatives for which hedge accounting is not applied are recognized in current earnings. The Company formally documents at inception all relationships between the derivative instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transactions. This process includes linking all derivatives that are designated as hedges to specific assets and liabilities, or to specific firm commitments. The Company also formally assesses, both at inception of the hedge and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in the fair values or cash flows of the hedged items. If it is determined that a derivative is not highly effective or has ceased to be a highly effective hedge, the Company would discontinue hedge accounting prospectively. Gains or losses resulting from the termination of a derivative accounted for as a cash flow hedge remain in other comprehensive income (loss) and is (accreted) amortized to earnings over the remaining period of the former hedging relationship. Certain derivative financial instruments are offered to certain commercial banking customers to manage their risk of exposure and risk management strategies. These derivative instruments consist primarily of currency forward contracts and interest rate swap contracts. The risks associated with these transactions is mitigated by simultaneously entering into similar transactions having essentially offsetting terms with a third party. In addition, the Company executes interest rate swaps with third parties in order to hedge the interest rate risk of short-term FHLB advances. Currency Forward Contracts. At December 31, 2023 and 2022, the Company had no currency forward contracts in place with commercial banking customers. Interest Rate Swaps. At December 31, 2023 and December 31, 2022, the Company had 80 and 54 interest rate swaps in place with commercial banking customers executed by offsetting interest rate swaps with third parties, with aggregated notional amounts of $277.8 million and $205.0 million, respectively. These derivatives are not designated as hedges and are not speculative. These interest rate swaps do not meet hedge accounting requirements. At December 31, 2023 and 2022, the Company had 30 and 20 interest rate swaps with notional amounts of $380.0 million and $290.0 million, respectively, hedging certain FHLB advances. These interest rate swaps meet the cash flow hedge accounting requirements. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counter-party in exchange for the Company making fixed-rate payments over the life of the agreements without the exchanges of the underlying notional amount. At December 31, 2023, and 2022, the Company had two interest rate swaps hedged against pools of floating rate commercial loans with notional amounts totaling $100.0 million. These swaps meet the cash flow hedge accounting requirements. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counter-party in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. At December 31, 2023, the Company had eight interest rate fair value swaps with notional amounts totaling $700.0 million. The Company is exposed to changes in the fair value of certain of its fixed-rate pools of assets due to changes in benchmark interest rates. The Company uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate of SOFR. At December 31, 2022, the Company did not have any fair value swaps. (21) Derivatives and Hedging Activities (continued) Interest rate swaps designated as fair value hedges involve the payment of fixed-rate amounts to a counterparty in exchange for the Company receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. For the year ended December 31, 2023, the Company recorded hedge ineffectiveness associated with these contracts totaling approximately $47,000. For the years ended December 31, 2022 and 2021, the Company did not record any hedge ineffectiveness associated with these contracts. The tables below present the fair value of the Company’s derivative financial instruments as well as their classification in the Consolidated Statements of Financial Condition at December 31, 2023 and 2022:
For the years ended December 31, 2023, 2022, and 2021 gains (losses) of $(302,000), $489,000, and $115,000 respectively, were recorded for changes in fair value of interest rate swaps with third parties. At December 31, 2023 and 2022, accrued interest was $1.2 million and $22,000. The Company has agreements with counterparties that contain a provision that if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default of its derivative obligations. At December 31, 2023, the termination value of derivatives in a net liability position, which includes accrued interest, was $6.1 million. The Company has collateral posting thresholds with certain of its derivative counterparties and has posted collateral of $2.4 million against its obligations under these agreements. (21) Derivatives and Hedging Activities (continued) Fair Value Hedges of Interest Rate Risk. The Company is exposed to changes in the fair value of certain of its fixed-rate pools of assets due to changes in benchmark interest rates. The Company uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate, SOFR. Interest rate swaps designated as fair value hedges involve the payment of fixed-rate amounts to a counterparty in exchange for the Company receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in interest income. At December 31, 2023, the following amounts were recorded on the Consolidated Statements of Financial Condition related to cumulative basis adjustment for fair value hedges:
At December 31, 2022, the Company had no fair value hedges.

| Revenue Recognition | Revenue Recognition The Company's revenue includes net interest income on financial instruments and non-interest income. Most of the Company's revenue is not within the scope of Accounting Standards Codification Topic 606 which does not apply to revenue associated with financial instruments, including interest income on loans and securities, which comprise the majority of the Company's revenue. Revenue-generating activities that are within the scope of this guidance are components of non-interest income. These revenue streams can generally be classified as demand deposit account fees, title insurance fees, insurance agency income and other fees. The following table presents non-interest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the years ended December 31, 2023, 2022, and 2021.
Demand deposit account fees include monthly maintenance fees and service charges. These fees are generally derived as a result of either transaction-based or serviced-based services. The Company's performance obligation for these services is generally satisfied, and revenue recognized, at the time the transaction is completed, or the service rendered. Fees for these services are generally received from the customer either at the time of the transaction or monthly. Title insurance fees are generally recognized at the time the transaction closes or when the service is rendered. RSI Insurance Agency, Inc. performs the function of an insurance intermediary, by introducing the policyholder and insurer for life and health, and property and casualty insurance, and is compensated by a commission fee for placement of an insurance policy. Commission and fees are generally recognized as of the effective date of the insurance policy. Commission revenues related to installment billings are recognized on the invoice date. Subsequent commission adjustments are recognized upon the receipt of notification from insurance companies concerning matters necessitating such adjustments. Other non-interest income includes check printing fees, traveler's check fees, gift card fees, branch service fees, overdraft fees, account analysis fees, other deposit related fees, wealth management related fee income which includes annuity fees, brokerage commissions, and asset management fees. Wealth management related fee income represent fees earned from customers as consideration for asset management and investment advisory services provided by a third party. The Company's performance obligation is generally satisfied monthly, and the resulting fees are recognized monthly based upon the month-end market value of the assets under management and the applicable fee rate. The Company does not earn performance-based incentives. The Company's performance obligation for these transaction-based services are generally satisfied, and related revenue recognized, at the time the transaction closes or when the service is rendered or a point in time when the service is completed. Also included in other fees are debit card and ATM fees which are transaction-based. Debit card revenue is primarily comprised of interchange fees earned when a customer's Company card is processed through a card payment network. ATM fees are largely generated when a Company cardholder uses a non-Company ATM, or a non-Company cardholder uses a Company ATM. The Company's performance obligation for these services is satisfied when the service is rendered. Payment is generally received at time of transaction or monthly. Out-of-scope non-interest income primarily consists of income from bank-owned life insurance, loan prepayment and servicing fees, net fees on loan level swaps, gains and losses on the sale of loans and securities, credit card interchange income, changes in the fair value of equity securities, and proceeds from an insurance settlement. None of these revenue streams are subject to the requirements of Topic 606.

| Subsequent Events | Subsequent Events The Company has evaluated events subsequent to December 31, 2023 and through the financial statement issuance date of February 29, 2024. In February 2024, we received notification from the FDIC that the estimated loss attributable to the protection of uninsured depositors at Silicon Valley Bank and Signature Bank is $20.4 billion, an increase of approximately $4.1 billion from the estimate of $16.3 billion described in the final rule. (See Regulation/Supervision - “Insurance of Deposit Accounts” for additional information.) The FDIC plans to provide institutions subject to the special assessment an updated estimate of each institution’s quarterly and total special assessment expense with its first quarter 2024 special assessment invoice, to be released in June 2024. The Company cannot reasonably estimate the additional assessment amount at this time.

| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Principles of Consolidation | Principles of Consolidation The accompanying consolidated financial statements include the accounts of Columbia Financial, Inc., its wholly-owned subsidiaries, Columbia Bank ("Columbia"), Freehold Bank ("Freehold"), and Columbia's wholly-owned subsidiaries, Columbia Investment Services, Inc., 2500 Broadway Corp., 1901 Residential Management Co. LLC, First Jersey Title Services, Inc., 1901 Commercial Management Co. LLC, Stewardship Realty LLC, CSB Realty Corp., and RSI Insurance Agency, Inc., (collectively, the “Company”). The accounts of the MHC are not consolidated in the consolidated financial statements of the Company. In consolidation, all intercompany accounts and transactions are eliminated. Certain reclassifications have been made in the consolidated financial statements to conform with current year classifications. The Company also owns 100% of the common stock of Stewardship Statutory Trust I, which is a trust incorporated in Delaware which was also acquired in the Company's merger with Stewardship in November 2019. In accordance with ASC Topic 810, Consolidation, this Trust was classified as a variable interest entity and did not satisfy the conditions for consolidation. Accordingly, this Trust, which owns $7.0 million of trust preferred securities, which represents 100% of the assets, is treated as an unconsolidated subsidiary.
|
| Basis of Financial Statement Presentation | Basis of Financial Statement Presentation The consolidated financial statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), including the elimination of all significant intercompany accounts and transactions during consolidation. In preparing the consolidated financial statements, management is required to make estimates, significant judgments and assumptions that affect the reported amounts of assets and liabilities as of the dates of the Consolidated Statements of Financial Condition and Consolidated Statements of Income for the periods presented. Actual results could differ from these judgments and estimates under different conditions, resulting in a change that could have a material impact on the carrying values of our assets and liabilities and our results of operations. Material estimates that involve significant judgements and assumptions that are particularly susceptible to change are the determination of the adequacy of the allowance for credit losses, evaluation of goodwill for impairment, evaluation of other-than-temporary impairment on securities, evaluation of the need for valuation allowances on deferred tax assets, and determination of liabilities related to retirement and other post-retirement benefits. These estimates, significant judgements and assumptions are evaluated on an ongoing basis and are adjusted when facts and circumstances dictate. Illiquid credit markets, volatile securities markets, and declines in the housing market and the economy generally have combined to increase the uncertainty inherent in such estimates and assumptions. Changes in estimates resulting from continuing changes in the economic environment will be reflected in the consolidated financial statements in future periods.
|
| Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks, interest-bearing deposits at other financial institutions and short-term investments.
|
| Securities | Securities Securities are classified as available for sale and held to maturity. Management determines the appropriate classification of securities at the time of purchase. Securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and reported at amortized cost. Securities not classified as held to maturity are classified as available for sale and carried at estimated fair value, with unrealized holding gains or losses, net of taxes, reported as a separate component of accumulated other comprehensive income or loss ("OCI") included in stockholders' equity. Effective January 1, 2022, the Company adopted the provisions of ASC 326 and modified its accounting policy for the assessment of available for sale securities for impairment. Under ASC 326 for available for sale securities, the Company first assesses whether a loss is from credit or other factors and considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost, a credit loss would be recorded through an allowance for credit losses, limited by the amount that the fair value is less than the amortized cost basis. The fair values of these securities are based on market quotations or matrix pricing as discussed in note 17. The Company evaluates securities for other-than-temporary impairment at each reporting period and more frequently when economic or market conditions warrant such evaluation. In this evaluation, if such declines were deemed other-than temporary, management would measure the total credit-related component of the unrealized loss and recognize that portion of the loss as a charge to current period earnings. The remaining portion of the unrealized loss would be recognized as an adjustment to OCI. The fair value of the securities portfolio is significantly affected by changes in interest rates. In general, as interest rates rise, the fair value of fixed-rate securities decreases and as interest rates fall, the fair value of fixed-rate securities increases. The Company determines if it has the intent to sell securities or if it more likely than not that the Company would be required to sell the securities before the anticipated recovery. If either exists, the decline in value is considered other-than-temporary and would be recognized in current period earnings. Premiums and discounts on securities are generally amortized and accreted to income over the contractual lives of the securities using the level-yield method. Premiums on callable securities are amortized to the earliest call date. Dividend and interest income are recognized when earned. Realized gains and losses are recognized when securities are sold or called based on the specific identification method. In the ordinary course of business, securities are pledged as collateral in conjunction with the Company’s borrowings, lines of credit, and public funds on deposit.
|
| Federal Home Loan Bank Stock | Federal Home Loan Bank Stock The Banks, as members of the Federal Home Loan Bank of New York (the "FHLB"), are required to hold shares of capital stock of the FHLB based on its activities, primarily its outstanding borrowings. The investment is carried at cost, or par value, which approximates fair value. Cash dividends are reported as income.
|
| Loans Held-for-Sale | Loans Held-for-Sale Loans held-for-sale consists of loans intended for sale in the secondary market. These loans are carried at the lower of cost or estimated fair value, less costs to sell, as determined on an individual loan basis. Net unrealized losses, if any, are recognized in a valuation allowance through a charge to earnings. Origination fees and costs on loans held-for-sale are deferred and recognized on settlement dates as a component of the gain or loss on sale. Loans held-for-sale are generally sold with loan servicing rights retained by Columbia Bank.
|
| Loans Receivable and Purchased Credit-Deteriorated ("PCD") Loans | Loans Receivable Loans receivable are carried at unpaid principal balances adjusted by unamortized premiums and unearned discounts, net deferred origination fees and costs, purchase accounting fair value adjustments and the allowance for credit losses. The Company defers loan origination fees and certain direct loan origination costs and accretes such amounts as an adjustment to the yield over the expected lives of the related loans using the level-yield method. Interest income on loans is accrued on unpaid principal balances and credited to income as earned. Premiums and discounts on loans purchased are amortized or accreted as an adjustment to yield over the contractual lives of the related loans using methodologies which approximate the level-yield method. A loan is considered delinquent when payment has not been received within 30 days of its contractual due date. Generally, a loan in designated as a non-accrual loan when the payment of interest is 90 days or more in arrears of its contractual due date. When a loan is placed on non-accrual status, any interest accrued but not received is reversed against interest income. Payments received on a non-accrual loan are either applied to the outstanding principal balance or recorded as interest income, depending on an assessment of the ability to collect the loan. Non-accruing loans are returned to accrual status after there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible. The Company identifies loans that may need to be charged-off as a loss, by reviewing all delinquent loans, classified loans and other loans that management may have concerns about collectability. On a case-by-case basis, the Company may evaluate individual loans for which it is probable, based on current information, that the Company will not collect all amounts due under the contractual terms of the loan agreement. The Company considers the population of loans in its analysis to include all multifamily and commercial real estate, construction, and commercial business loans with an outstanding balance greater than $500,000 and not accruing interest, and loan modifications. The Company also considers residential real estate, and home equity loans and advances that are not accruing or modified. Other loans may be included in the population of loans to be evaluated if management has specific information of a collateral shortfall. Loans individually analyzed are measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral if the loan is collateral dependent. Payments received on individually analyzed loans are recognized on a cash basis. Purchased Credit-Deteriorated ("PCD") Loans Loans acquired in a business combination that have experienced more-than-insignificant deterioration in credit quality since origination are considered purchased with credit deterioration (“PCD”) loans. The Company evaluated acquired loans for deterioration in credit quality based on any of, but not limited to, the following: (1) non-accrual status; (2) previously a troubled debt restructured designation; (3) risk ratings of special mention, substandard or doubtful; and (4) delinquency status. At the acquisition date, an estimate of expected credit losses was made for groups of PCD loans with similar risk characteristics and individual PCD loans without similar risk characteristics. This initial allowance for credit losses is allocated to individual PCD loans and added to the purchase price or acquisition date fair values to establish the initial amortized cost basis of the PCD loans. As the initial allowance for credit losses is added to the purchase price, there is no credit loss expense recognized upon acquisition of a PCD loan. Any difference between the unpaid principal balance of PCD loans and the amortized cost basis is considered to relate to noncredit factors and results in a discount or premium. Discounts and premiums are recognized through interest income on a level-yield method over the life of the loans. For acquired loans not deemed PCD at acquisition, the differences between the initial fair value and the unpaid principal balance are recognized as interest income on a level-yield basis over the lives of the related loans. At the acquisition date, an initial allowance for expected credit losses is estimated and recorded as credit loss expense. On January 1, 2022, the Company adopted CECL (ASC Topic 326), which replaced the historical incurred loss methodology with an expected loss methodology. The loan portfolio segmentation was expanded to seven portfolio segments taking into consideration common loan attributes and risk characteristics, as well as historical reporting metrics and data availability. The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of loans receivable. Accrued interest receivable on loans receivable is reported as a component of in the Consolidated Statements of Financial Condition, which totaled $32.9 million and $29.4 million at December 31, 2023 and 2022, respectively and is excluded from the estimate of credit losses. Refer to note 2, Summary of Significant Accounting Policies for additional information on the adoption of Topic 326 and CECL methodology. The allowance for credit losses on loans ("ACL") is established through the provision for credit losses that are charged to income, which is based upon an evaluation of estimated losses in the current loan portfolio, including the evaluation of individually analyzed loans. Charge-offs against the ACL are taken on loans where management determines that the collection of loan principal and interest is unlikely. Recoveries made on loans that have been charged-off are credited to the ACL. Although we believe we have established and maintained the ACL on loans at appropriate levels, changes in reserves may be necessary if actual economic and other conditions differ substantially from the forecast used in estimating the ACL.

| Allowance for Credit Losses on Loans Receivable and on Unfunded Commitments and Modification of Loans ("Modifications") | Allowance for Credit Losses on Loans Receivable The determination of the allowance for credit losses (“ACL”) on loans is considered a critical accounting estimate by management because of the high degree of judgment involved in determining qualitative loss factors, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment The ACL is maintained at a level management considers adequate to provide for estimated losses and impairment based upon an evaluation of known and inherent risk in the loan portfolio. The ACL consists of two elements: (1) identification of loans that must be individually analyzed for impairment and (2) establishment of an ACL for loans collectively analyzed. Management estimates the ACL using relevant and reliable information from internal and external sources, related to past events, current conditions, and a reasonable and supportable forecast. Historical credit loss experience for both the Company and its segment-specific peers provides the basis for the estimate of expected credit losses. Credit losses over a defined period are converted to PD rate curves through the use of segment-specific LGD risk factors that convert default rates to loss severity based on industry-level, observed relationships between the two variables for each segment, primarily due to the nature of the underlying collateral. These risk factors were assessed for reasonableness against the Company’s own loss experience and adjusted in certain cases when the relationship between the Company’s historical default and loss severity deviate from that of the wider industry. The historical PD curves, together with corresponding economic conditions, establish a quantitative relationship between economic conditions and loan performance through an economic cycle. Portfolio segments are defined as the level at which an entity develops and documents a systematic methodology to determine its allowance for credit losses. Management developed segments for estimating losses based on the type of borrower and collateral which is generally based upon federal call report segmentation. The segments have been combined or sub-segments have been added as needed to ensure loans of similar risk profiles are appropriately pooled. We maintain a loan review system that provides a periodic review of the loan portfolio and the identification of individually analyzed loans. The ACL for individually analyzed loans is based on the fair value of collateral or cash flows. While management uses the best information available to make such evaluations, future adjustments to the allowance may be necessary if economic conditions differ substantially from the assumptions used in making the evaluations. The ACL quantitative allowance for each segment is measured using a discounted cash flow methodology incorporating an econometric, probability of default (“PD”) and loss given default (“LGD”) with distinct segment-specific multi-variate regression models applied. Expected credit losses are estimated over the life of the loans by measuring the difference between the net present value of modeled cash flows and amortized cost basis. Contractual cash flows over the contractual life of the loans are the basis for the modeled cash flows, adjusted for model defaults and expected prepayments and discounted at the loan-level effective interest rate. The contractual term excludes expected extensions, renewals, and modifications. Management estimates the ACL using relevant and reliable information from internal and external sources, related to past events, current conditions, and a reasonable and supportable forecast. Historical credit loss experience for both the Company and its segment-specific peers provides the basis for the estimate of expected credit losses. Credit losses over a defined period are converted to PD rate curves through the use of segment-specific LGD risk factors that convert default rates to loss severity based on industry-level, observed relationships between the two variables for each segment, primarily due to the nature of the underlying collateral. These risk factors were assessed for reasonableness against the Company’s own loss experience and adjusted in certain cases when the relationship between the Company’s historical default and loss severity deviate from that of the wider industry. The historical PD curves, together with corresponding economic conditions, establish a quantitative relationship between economic conditions and loan performance through an economic cycle. Using the historical relationship between economic conditions and loan performance, management’s expectation of future loan performance is incorporated using a single economic forecast of macroeconomic variables (i.e., unemployment, gross domestic product, vacancy, and home price index). This forecast is applied over a period that management has determined to be reasonable and supportable. Beyond the period over which management can develop or source a reasonable and supportable forecast, the model reverts to long-term average historical loss rates using a straight-line, time-based methodology. The Company's current forecast period is six quarters, with a four-quarter reversion period to long-term average historical loss rates. After quantitative considerations, management applies additional qualitative adjustments that consider the expected impact of certain factors not fully captured in the quantitative reserve. Qualitative adjustments include but are not limited to concentrations of large loan balances, delinquency trends, change in collateral values within segments, and other considerations. (2) Summary of Significant Accounting Policies (continued) Allowance for Credit Losses on Loans Receivable (continued) The ACL is established through the provision for credit losses that are charged to income, which is based upon an evaluation of estimated losses in the current loan portfolio, including the evaluation of individually analyzed loans. Charge-offs against the ACL are taken on loans where management determines that the collection of loan principal and interest is unlikely. Recoveries made on loans that have been charged-off are credited to the ACL. Although we believe we have established and maintained the ACL on loans at appropriate levels, changes in reserves may be necessary if actual economic and other conditions differ substantially from the forecast used in estimating the ACL. Our financial results are affected by the changes in and the level of the ACL. This process involves our analysis of internal and external variables, and it requires that we exercise judgment to estimate an appropriate ACL. As a result of the uncertainty associated with this subjectivity, we cannot assure the precision of the amount reserved, should we experience sizable loan losses in any particular period and/or significant changes in assumptions or economic condition. We believe the primary risks inherent in the portfolio are a general decline in the economy, a decline in real estate market values, rising unemployment, increasing vacancy rates, and increases in interest rates in the absence of economic improvement or any other such factors. Any one or a combination of these events may adversely affect a borrower's ability to repay its loan, resulting in increased delinquencies and loan losses. Accordingly, we have recorded loan credit losses at a level which is estimated to represent the current risk in its loan portfolio. Most of our non-performing assets are collateral dependent loans which are written down to the fair value of the collateral less estimated costs to sell. We continue to assess the collateral of these loans and update our appraisals on these loans on an annual basis. To the extent the property values decline, there could be additional losses on these non-performing assets, which may be material. Management considered these market conditions in deriving the estimated ACL. Should economic difficulties occur, the ultimate amount of loss could vary from our current estimate. Allowance for Credit Losses on Unfunded Commitments The Company is required to include unfunded commitments that are expected to be funded in the future within the allowance for credit loss calculation, other than those that are unconditionally cancellable. To arrive at that reserve, the reserve percentage for each applicable segment is applied to the unused portion of the expected commitment balance and is multiplied by the expected funding rate. To determine the expected funding rate, the Company uses a historical utilization rate for each segment. The allowance for credit losses for off-balance-sheet exposures is reported in other liabilities in the Consolidated Statements of Financial Condition. The liability represents an estimate of expected credit losses arising from off-balance-sheet exposures such as unfunded commitments. Modification of Loans ("Modifications") On January 1, 2023, the Company adopted ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures which eliminated the accounting guidance for troubled debt restructurings ("TDR's") while enhancing disclosure requirements for certain loan refinancing and restructuring by creditors when a borrower is experiencing financial difficulty. This guidance was applied on a prospective basis. Modifications made to borrowers experiencing financial difficulty may include principal or interest forgiveness, forbearance, interest rate reductions, term extensions, or a combination of these events intended to minimize economic loss and avoid foreclosure or repossession of collateral. The Company evaluates whether the modifications represent a new loan or a continuation of an existing loan. A modification or refinancing results in a new loan if the terms of the new loan are at least favorable to the Company and customers with similar collection risks who are not refinancing or restructuring their loan, and the modification to the terms of the loan are deemed to be more than minor. A modification is considered to be more than minor if the difference between the present value of the cash flows of the new obligation and the remaining cash flows of the original obligation, both discounted using the effective interest rate of the original debt, is 10% or greater. If a modification does not meet the definition of a new loan, the modified loan will be treated as a continuation of the existing loan and all unamortized net fees and/or costs, and any prepayment penalties will be carried forward as part of the net new loan balance. (2) Summary of Significant Accounting Policies (continued) Modification of Loans ("Modifications") (Continued) Modified loans that were accruing prior to their modification where income was reasonably assured subsequent to the modification, maintain their accrual status. Modified loans for which collectability was not reasonably assured, are placed on non-accrual status, interest accruals cease, and uncollected accrued interest is reversed and charged against current income. Non-accruing modified loans may be returned to accrual status when there is a sustained period of repayment performance (generally six consecutive months of payments), and both principal and interest are deemed collectible.
|
| Loans Sold and Serviced | Loans Sold and Serviced The Company has entered into guarantor swaps with Freddie Mac which results in improved liquidity. In these types of transactions, the Company sells mortgage loans in exchange for Freddie Mac Mortgage Participation Certificates backed exclusively by the loans sold. The Company retains the servicing of these loans. The Company also periodically sells loans to investors and continues to service such loans for a fee. Gains or losses on the sale of loans are recorded on trade date using the specific-identification method.
|
| Office Properties and Equipment | Office Properties and Equipment Land is carried at cost. Office properties, land and building improvements, furniture and equipment, and leasehold improvements are carried at cost, less accumulated depreciation and amortization. Depreciation and amortization of office properties and equipment is computed on a straight-line basis over their estimated useful lives (generally 40 years for buildings, 10 years to 20 years for land and building improvements, 3 years to 10 years for furniture and equipment). Leasehold improvements, carried at cost, net of accumulated depreciation, are amortized over the terms of the related leases or the estimated useful lives of the assets, whichever is shorter. Major improvements are capitalized, while repairs and maintenance costs are charged to expense as incurred. Upon retirement or sale, any gain or loss is recognized as incurred.
|
| Bank-owned Life Insurance | Bank-owned Life Insurance ("BOLI") Bank-owned life insurance is accounted for using the cash surrender value method and is recorded at its net realizable value. The change in the net asset value is recorded as a component of non-interest income. A deferred liability has been recorded for the estimated cost of post-retirement life insurance benefits accruing to applicable employees and directors covered by an endorsement split-dollar life insurance arrangement.
|
| Goodwill and Intangible Assets | Goodwill and Intangible Assets Intangible assets of the Company consist of goodwill, core deposit intangibles and mortgage servicing rights. Goodwill represents the excess of the purchase price over the fair value of net assets acquired in purchase acquisitions. In accordance with GAAP, goodwill with an indefinite useful life is not amortized, but is evaluated for impairment on an annual basis, or more frequently if events or changes in circumstances indicate potential impairment between annual measurement dates. As permitted by GAAP, the Company prepares a qualitative assessment in determining whether goodwill may be impaired. The factors considered in the assessment include macroeconomic conditions, industry and market conditions and overall financial performance of the Company, among others. The Company completed its annual goodwill impairment test as of December 31, 2023, based upon its qualitative assessment of goodwill and concluded that goodwill was not impaired and no further quantitative analysis was warranted. Core deposit intangibles represent the intangible value of depositor relationships acquired by the Company through purchase acquisitions of Stewardship, Freehold and RSI. The premiums ascribed to these deposits are amortized over their estimated useful lives. Mortgage servicing rights are recorded when purchased or when originated mortgage loans are sold, with servicing rights retained. Mortgage servicing rights are amortized on an accelerated method based upon the estimated lives of the related loans, and generally adjusted for prepayments. Mortgage servicing rights are carried at the lower of amortized cost or fair value.
|
| Leases | Leases The Company determines if an arrangement is a lease at inception. The Company's leases primarily relate to real estate property for branches and office space. All the Company's leases are classified as operating leases and the related right-of-use asset ("ROU") and lease liability are included in other assets and , respectively on the Consolidated Statements of Financial Condition. ROU assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease arrangements. The calculated amounts of the ROU asset and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of minimum lease payments. As the Company's leases do not provide an implicit rate, the discount rate used in determining the lease liability for each individual lease is the Company's incremental borrowing rate. The present value of the lease liability may include the impact of options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options provided in the lease terms. Lease expense is recognized on a straight-line basis over the expected lease term, while variable lease payments are recognized as incurred. Lease agreements that include lease and non-lease components, such as common area maintenance charges, are accounted for separately.

| Post-retirement Benefits | Post-retirement Benefits The Company provides certain health care and life insurance benefits to eligible retired employees under a Post-retirement Plan. The Company accrues the cost of retiree health care and other benefits during the employee's period of active service. Effective January 1, 2019, the Post-retirement Plan has been closed to new hires. Through the acquisition of the RSI Entities, the Company acquired a non-funded Post-retirement plan. This defined benefit post-retirement healthcare plan covers substantially all retirees and employees.
|
| Employee Benefits Plans | Employee Benefit Plans The Company maintains a single employer, tax-qualified defined benefit pension plan (the "Pension Plan") which covers full-time employees that satisfy the Pension Plan's eligibility requirements. The benefits are based on years of service and the employee's average compensation for the highest consecutive years of employment. Effective October 1, 2018, newly hired employees are not eligible to participate in the Pension Plan as the Pension Plan has been closed to new employees as of that date. The policy is to fund at least the minimum contribution required by the Employee Retirement Income Security Act of 1974. GAAP requires an employer to: (a) recognize in its statement of financial position the over-funded or under-funded status of a defined benefit post-retirement plan measured as the difference between the fair value of plan assets and the benefit obligation; (b) measure a plan’s assets and its obligations that determine its funded status at the end of the employer’s fiscal year (with limited exceptions); and (c) recognize as a component of other comprehensive income (loss), net of tax, the actuarial gains and losses and the prior service costs and credits that arise during the period. The assets of the plan are primarily invested in fixed income and equity funds. Through the acquisition of the RSI Entities on May 1, 2022, the Company acquired a funded pension plan. The benefits are based on years of service and the employee’s compensation, as defined. The Plan was amended effective March 31, 2011, to freeze the Plan so that no employee shall commence or recommence participation in the Plan, that there shall be no further benefit accruals under the Plan, and that compensation received after the effective date shall not be recognized for any purpose under the Plan. Effective September 30, 2023, the RSI Pension Plan was merged into the Columbia Bank Pension Plan. The Company also maintains a Retirement Income Maintenance Plan (the "RIM Plan") which is a non-qualified defined benefit plan which provides benefits to all employees of the Company if their benefits under the Pension Plan are limited by Internal Revenue Code Sections 415 and 401(a)(17). Columbia Bank and Freehold Bank each have a 401(k) plan covering substantially all employees. Columbia Bank may match a percentage of the first 3.00% to 4.50% contributed by participants. Columbia's matching contribution, if any, is determined by their Board of Directors in its sole discretion. Freehold does not presently match any portion of employee contribution but may provide an annual match determined by their Board of Directors in its sole discretion. (2) Summary of Significant Accounting Policies (continued) Employee Benefit Plans (continued) Columbia Bank has an Employee Stock Ownership Plan ("ESOP"). The funds borrowed by the ESOP from the Company to purchase the Company's common stock are being repaid from Columbia Bank's contributions over a period of 20 years. The Company's common stock not allocated to participants is recorded as a reduction of stockholders' equity at cost. Compensation expense for the ESOP is based on the average price of the Company's stock and the amount of shares committed to be allocated during each period. Columbia Bank has a Supplemental Executive Retirement Plan ("SERP"). The SERP is a non-qualified plan which provides supplemental retirement benefits to eligible officers (those designated by the Board of Directors) of the Company who are prevented from receiving the full benefits contemplated by the ESOP's benefit formulas under tax law limits for tax-qualified plans. In addition, the Company maintains a stock based deferral plan (the "Stock Based Deferral Plan") for certain executives and directors. The Company records a deferred compensation equity account and corresponding contra-equity account for the cost of the shares held by the Stock Based Deferral and SERP Plans. Columbia Bank also maintains a non-qualified savings income maintenance deferred compensation plan (the "SIM Plan") that provides supplemental benefits to certain executives who are prevented from receiving the full benefits contemplated by the 401(k) Plan under tax law limits for tax-qualified plans, and a Deferred Compensation Plan for directors. Freehold Bank also sponsors a directors retirement plan, a director and executive deferred compensation plan, and a supplemental executive retirement plan for certain current and former directors and officers of the Bank. Through the acquisition of the RSI Entities, the Company also acquired an executive incentive retirement plan, a board of director and executive deferred compensation plan, a supplemental executive retirement plan, a key life insurance plan and a split-dollar life insurance plan for certain current and former directors and officers of the Bank.

| Derivatives | Derivatives The Company uses derivative financial instruments as components of its market risk management, principally to manage interest rate risk. Certain derivatives are entered into in connection with transactions with commercial customers. Derivatives are not used for speculative purposes. All derivatives are recognized as either assets or liabilities in the Consolidated Statements of Financial Condition, reported at fair value and presented on a gross basis. Until a derivative is settled, a favorable change in fair value results in an unrealized gain that is recognized as an asset, while an unfavorable change in fair value results in an unrealized loss that is recognized as a liability. The Company generally applies hedge accounting to its derivatives used for market risk management purposes. Hedge accounting is permitted only if specific criteria are met, including a requirement that a highly effective relationship exists between the derivative instrument and the hedged item, both at inception of the hedge and on an ongoing basis. Changes in the fair value of effective fair value hedges are recognized in current earnings (with the change in fair value of the hedged asset or liability also recognized in earnings). Changes in the fair value of effective cash flow hedges are recognized in other comprehensive income (loss) until earnings are affected by the variability in cash flows of the designated hedged item. Ineffective portions of hedge results are recognized in current earnings. Changes in the fair value of derivatives for which hedge accounting is not applied are recognized in current earnings. The Company formally documents at inception all relationships between the derivative instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transactions. This process includes linking all derivatives that are designated as hedges to specific assets and liabilities, or to specific firm commitments. The Company also formally assesses, both at inception of the hedge and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in the fair values or cash flows of the hedged items. If it is determined that a derivative is not highly effective or has ceased to be a highly effective hedge, the Company would discontinue hedge accounting prospectively. Gains or losses resulting from the termination of a derivative accounted for as a cash flow hedge remain in other comprehensive income (loss) and is (accreted) amortized to earnings over the remaining period of the former hedging relationship. (2) Summary of Significant Accounting Policies (continued) Derivatives (continued) Certain derivative financial instruments are offered to certain commercial banking customers to manage their risk of exposure and risk management strategies. These derivative instruments consist primarily of currency forward contracts and interest rate swap contracts. The risks associated with these transactions is mitigated by simultaneously entering into similar transactions having essentially offsetting terms with a third-party. In addition, the Company executes interest rate swaps with third parties in order to hedge the interest rate risk of short-term FHLB advances.

| Income Taxes | Income Taxes The Company and its subsidiaries file consolidated federal income tax returns. Federal income taxes are allocated to each entity based on their respective contributions to taxable income of the consolidated income tax returns. Separate state income taxes are filed for the Company and its subsidiaries on either a consolidated or unconsolidated basis as required by each jurisdiction. The Company records income taxes in accordance with ASC Topic 740, Income Taxes, using the asset and liability method. Federal and state income taxes have been provided on the basis of the Company's income or loss as reported in accordance with GAAP. The amounts reflected on the Company's federal and state income tax returns differ from these provisions due principally to temporary differences in the reporting of certain items for consolidated financial statement reporting and income tax reporting purposes. Accordingly, deferred tax assets and liabilities: (i) are recognized for the estimated future tax consequences of events that have been recognized in the financial statements or tax returns; (ii) are attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases; and (iii) are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Where applicable, deferred tax assets are reduced by a valuation allowance for any portions determined not likely to be realized based on the nature and timing of these items. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income tax expense in the period that includes the enactment date. The valuation allowance is adjusted, by a charge or credit to income tax expense, as changes in facts and circumstances warrant. The Company did not have any liabilities for uncertain tax positions or any known unrecognized tax benefits at December 31, 2023 and 2022. The Company policy is to recognize interest and penalties related to unrecognized tax benefits in income tax expense in the Consolidated Statements of Income. The Company did not recognize any interest and penalties during the years ended December 31, 2023, 2022 and 2021. On July 1, 2018, New Jersey enacted legislation which adds to the state’s 9.0% Corporation Business Tax rate (i) a 2.5% surtax for periods beginning in 2018 and 2019 and (ii) a 1.5% surtax for periods beginning in 2020 and 2021. Subsequently, on September 12, 2020, New Jersey enacted legislation that restored and extended the 2.5% Corporation Business Tax surcharge to apply retroactively from January 1, 2020 through December 31, 2023. These surtaxes apply to corporations with more than $1.0 million of net income allocated to New Jersey.
|
| Comprehensive Income (Loss) | Comprehensive Income (Loss) Comprehensive income (loss) consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes items recorded in equity, such as unrealized gains and losses on debt securities available for sale, the noncredit component of other than temporary impairment losses on debt securities, unrealized gains and losses on derivatives, and the unfunded status and reclassification of actuarial net (loss) gain associated with the Company's benefit plans. Comprehensive income is presented in a separate Consolidated Statement of Comprehensive Income (Loss).
|
| Segment Reporting | Segment Reporting The Company’s operations are substantially in the financial services industry and include providing traditional banking and other financial services to its customers. The Company operates primarily in New Jersey. Management makes operating decisions and assesses performance based on an ongoing review of the Company’s consolidated financial results. Therefore, the Company has a single operating segment for financial reporting purposes.
|
| Earnings Per Share | Earnings Per Share ("EPS") Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. For purposes of calculating basic EPS, weighted average common shares outstanding excludes treasury stock, unallocated employee stock ownership plan shares that have not been committed for release and deferred compensation obligations required to be settled in shares of Company stock. Diluted EPS is computed using the same method as basic EPS and reflects the potential dilution which could occur if stock options and unvested shares were exercised and converted into common stock. The potentially diluted shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method. Shares issued and reacquired during any period are weighted for the portion of the period that they were outstanding.
|
| Stock Compensation Plans | Stock Compensation Plans Compensation expense related to stock options and non-vested restricted stock awards is based on the fair value of the award on the measurement date with expense recognized on a straight line basis over the requisite performance or service period. The fair value of stock options is estimated utilizing the Black-Scholes option pricing model. The fair value of non-vested restricted stock awards is generally the closing market price of the Company's common stock on the date of grant. The Company accounts for forfeitures as they occur.

| Accounting Pronouncements Adopted | Accounting Pronouncements Adopted In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method. The purpose of this updated guidance is to further align risk management objectives with hedge accounting results on the application of the last-of-layer method, which was first introduced in ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2022-01 is effective for public business entities for fiscal years beginning after December 15, 2022, with early adoption in the interim period, permitted. For entities who have already adopted ASU 2017-12, immediate adoption is allowed. ASU 2022-01 requires a modified retrospective transition method for basis adjustments in which the entity will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption. The Company adopted this ASU on January 1, 2023 on a prospective basis; therefore, there was no impact to the Company's consolidated financial statements. In March 2022, the FASB issued ASU 2022-02, Financial Instruments-Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures. ASU 2022-02 addresses areas identified by the FASB as part of its post-implementation review of the credit losses standard (ASU 2016-13) that introduced the CECL model. The amendments eliminated the accounting guidance for troubled debt restructurings by creditors that have adopted the CECL model and enhanced the disclosure requirements for loan refinancing and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require a public business entity to disclose current period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. For entities that have adopted ASU 2016-13, this ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company adopted this pronouncement effective January 1, 2023. The update was applied on a prospective basis to disclosures and did not have a significant impact on the Company's consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("CECL"), further amended by ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. Topic 326 pertains to the measurement of credit losses on financial instruments. This update requires the measurement of all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better determine their credit loss estimates. This update is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. This update was effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2019. (2) Summary of Significant Accounting Policies (continued) Accounting Pronouncements Adopted (continued The Company elected to defer the adoption of the CECL methodology until December 31, 2020 as permitted by the enacted Coronavirus Aid, Relief and Economic Security Act ("CARES Act"). In late December 2020, the Consolidated Appropriations Act, 2021 was enacted, and extended certain provisions of the CARES Act, which allowed the Company to extend the adoption of CECL until January 1, 2022. The Company elected to extend its adoption of CECL in accordance with this legislation, and adopted the above mentioned ASUs related to Financial Instruments -Credit Losses (Topic 326) using a modified retrospective approach. The Company adopted ASU 2016-13 on January 1, 2022 for all financial assets measured at amortized cost and off-balance- sheet credit exposures. Results for the year ended December 31, 2023 are presented under Accounting Standards Codification 326, Financial Instruments - Credit Losses, while prior period amounts continue to be reported with previously applicable GAAP and have not been restated. Effective January 1, 2022, the Company recorded a $12.1 million decrease in the allowance for credit losses on loans (previously allowance for loan losses), established a $353,000 allowance for credit losses on debt securities available for sale, and recorded a $5.5 million increase in the liability for off-balance-sheet credit exposures, which resulted in a total cumulative effect adjustment of $6.2 million, net of tax, and an increase to retained earnings.

| Business Combinations | Described below are the methods used to determine the fair values of the significant assets acquired and liabilities assumed in the Freehold and RSI acquisitions: Cash and cash equivalents. The estimated fair values of cash and cash equivalents approximate their stated face amounts, as these financial instruments are either due on demand or have short-term maturities. Debt securities available for sale. The estimated fair values of the debt securities were calculated utilizing Level 2 inputs. The majority of the acquired securities were fixed income instruments that are not quoted on an exchange but are traded in active markets. The prices for these instruments are obtained through an independent pricing service when available, or dealer market participants with whom the Company has historically transacted with for both purchases and sales of securities. The prices are derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, and the bond's terms and conditions, among other things. Management reviewed the data and assumptions used in pricing securities by its third-party provider to ensure the highest level of significant inputs are derived from market observable data. Loans receivable. The acquired loan portfolio was segregated into pools for valuation purposes primarily based on loan type, non-accrual status, and credit risk rating. The estimated fair values were computed by discounting the expected cash flows from the respective pools. Cash flows were estimated by using valuation models that incorporated estimates of current key assumptions such as prepayment speeds, default rates, and loss severity rates. The process included: (1) projecting monthly principal and/or interest cash flows based on the contractual terms of the loans, including both maturity and contractual amortization; (2) adjusting projected cash flows for expected losses and prepayments, where appropriate; (3) developing a discount rate based on the relative risk of the cash flows, considering the loan type, liquidity risk, the maturity of the loans, servicing costs, and a required return on capital; and (4) discounting the projected cash flows to a present value, to arrive at the calculated value of the loans. The methods used to estimate the fair values of loans are extremely sensitive to the assumptions and estimates used. While management attempted to use assumptions and estimates that best reflected the acquired loan portfolios and current market conditions, a greater degree of subjectivity is inherent in the values than in those determined in active markets. Office properties and equipment, net. The fair value of land and buildings was estimated using current appraisals. Acquired equipment was not material. Buildings are amortized over their estimated useful lives. Equipment is amortized or depreciated over their estimated useful lives usually ranging from to fifteen years. Bank-owned life insurance. Bank-owned life insurance is accounted for using the cash surrender value method and is recorded at its net realizable value. Goodwill. Goodwill is not amortized for book purposes: however, it is reviewed at least annually for impairment and is not deductible for tax purposes. Core deposit intangibles. Core deposit intangibles ("CDI") are the measure of the value of non-maturity deposits in a business combination. The fair value of the CDI was calculated utilizing the cost savings approach, the expected cost savings attributable to the core deposits funding relative to an alternative source of funding, using a discounted cash flow present value methodology. Key inputs and assumptions utilized in the discounted cash flow present value methodology include core deposit balances and rates paid, the cost of an additional funding source, the aggregate life of deposits and truncation points, non-interest deposit costs, and the immediate deposit outflow assumption. Deposits. The fair values of deposit liabilities with no stated maturity (i.e., non-interest-bearing and interest-bearing demand deposit accounts, money market and savings and club deposits) are equal to the carrying amounts payable on demand. The fair value of certificates of deposit represents contractual cash flows, discounted to present value using interest rates currently offered on deposits with similar characteristics and remaining maturities. |
| Fair Value Measurements | Debt Securities Available for Sale, at Fair Value For debt securities available for sale, fair value was estimated using a market approach. The majority of these securities are fixed income instruments that are not quoted on an exchange but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations, matrix pricing and discounted cash flow pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to a benchmark or to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. Discounted cash flows, a Level 3 input, is estimated by discounting the expected future cash flows using the current rates for securities with similar credit ratings and similar remaining maturities. As the Company is responsible for the determination of fair value, it performs quarterly analysis on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to assess the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in an adjustment in the prices obtained from the pricing service. The Company may hold debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. The Company classifies the estimated fair value of its loan portfolio as Level 3. Equity Securities, at Fair Value The Company holds equity securities that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. A trust preferred security that is not traded in an active market and Federal Home Loan Mortgage Corporation ("FHLMC") and Federal National Mortgage Association ("FNMA") preferred stock, are considered Level 2 instruments. In addition, Level 2 instruments include Atlantic Community Bankers Bank ("ACBB") stock, which is based on redemption at par value and can only be sold to the issuing ACBB or another institution that holds ACBB stock. (17) Fair Value Measurements (continued) Derivatives The Company records all derivatives included in and in the Consolidated Statements of Financial Condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. See note 21 for disclosures related to the accounting treatment for derivatives. The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs. Individually Analyzed Collateral Dependent Loans/Impaired Loans The fair value of collateral dependent loans that are individually analyzed or were previously deemed impaired is measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral if the loan is collateral dependent. For individually analyzed loans measured for impairment based on the fair value of the underlying collateral, fair value was estimated using a market approach. The Company measures the fair value of collateral underlying impaired loans primarily through obtaining independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraisers’ market knowledge and experience, as well as adjustments for estimated costs to sell between 6% and 8%. For non-collateral dependent loans, management estimates fair value using discounted cash flows based on inputs that are largely unobservable. The Company classifies these loans as Level 3 within the fair value hierarchy. Mortgage Servicing Rights, Net ("MSR"s") Mortgage servicing rights are carried at the lower of cost or estimated fair value. The estimated fair value of MSRs is obtained through an analysis of future cash flows, incorporating assumptions that market participants would use in determining fair value including market discount rates, prepayments speeds, servicing income, servicing costs, default rates and other market driven data, including the market's perception of future interest rate movements. The prepayment speed and the discount rate are considered two of the most significant inputs in the model. A significant degree of judgment is involved in valuing the mortgage servicing rights using Level 3 inputs. The use of different assumptions could have a significant effect on this fair value estimate. Other Fair Value Disclosures The Company is required to disclose estimated fair value of financial instruments, both assets and liabilities on and off the balance sheet, for which it is practicable to estimate fair value. A description of the valuation methodologies used for those assets and liabilities not recorded at fair value on a recurring or non-recurring basis are set forth below. Cash and Cash Equivalents For cash and due from banks, federal funds sold and short-term investments, the carrying amount approximates fair value due to their nature and short-term maturities. (17) Fair Value Measurements (continued) Debt Securities Held to Maturity For debt securities held to maturity, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to benchmark or to compare securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As the Company is responsible for the determination of fair value, it performs quarterly analysis on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to assess the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in an adjustment in the prices obtained from the pricing service. The Company also holds debt instruments issued by the U.S. government and U.S. government sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs within the fair value hierarchy. Federal Home Loan Bank Stock ("FHLB") The fair value of FHLB stock is based on redemption at par value and can only be sold to the issuing FHLB, to other FHLBs, or to other member banks. As such, the Company's FHLB stock is recorded at cost, or par value, and is evaluated for impairment each reporting period by considering the ultimate recoverability of the investment rather than temporary declines in value. The Company classifies the estimated fair value as Level 2 within the fair value hierarchy. Loans Receivable Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial mortgage, residential mortgage, commercial, construction, and consumer and other. Each loan category is further segmented into fixed and adjustable rate interest terms and into performing and non-performing categories. The fair value of performing loans was estimated using a combination of techniques, including a discounted cash flow model that utilizes a discount rate that reflects the Company's current pricing for loans with similar characteristics and remaining maturity, adjusted by an amount for estimated credit losses inherent in the portfolio at the balance sheet date. The rates take into account the expected yield curve, as well as an adjustment for prepayment risk, when applicable. The Company classifies the estimated fair value of its loan portfolio as Level 3. The fair value for significant non-performing loans was based on recent external appraisals of collateral securing such loans, adjusted for the timing of anticipated cash flows. The Company classifies the estimated fair value of its non-performing loan portfolio as Level 3. Deposits The fair value of deposits with no stated maturity, such as demand, money market, and savings and club deposits are payable on demand at each reporting date and classified as Level 2. The estimated fair value of certificates of deposit was based on the discounted value of contractual cash flows. The discount rate was estimated using the Company’s current rates offered for deposits with similar remaining maturities. The Company classifies the estimated fair value of its certificates of deposit portfolio as Level 2. Borrowings The fair value of borrowings was estimated by discounting future cash flows using rates available for debt with similar terms and maturities and is classified by the Company as Level 2 within the fair value hierarchy. (17) Fair Value Measurements (continued) Commitments to Extend Credit and Letters of Credit The fair value of commitments to extend credit and letters of credit was estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counter-parties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value estimates of commitments to extend credit and letters of credit are deemed immaterial. Limitations Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because limited markets exist for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Other significant assets and liabilities that are not considered financial assets or liabilities include goodwill and intangible assets, deferred tax assets and liabilities, office properties and equipment, and bank-owned life insurance.
